United Explorer vs Delta SkyMiles Gold vs Southwest Priority in 2026: Best US Airline Cobrand Card for Earn Rate

US airline cobrand cardholders earning under USD 100k dominate the category per CFPB 2025 credit card report, and the three biggest cobrands from United, Delta, and Southwest split earn rates between everyday spend, dining, and airline-direct spend with a real material USD 400 to USD 900 mile-value gap per year for a typical USD 25,000 spender. Choosing between the United Explorer, Delta SkyMiles Gold American Express, and Southwest Rapid Rewards Priority Credit Card in 2026 is not a matter of which is objectively best. It is a matter of which airline you fly most, which redemption engine (Star Alliance transfers, Delta dynamic, or Southwest cash-plus-tax) matches your travel pattern, and whether your card portfolio already includes a Chase Sapphire or Amex Gold. Here is the earn rate, benefits, and mile-value comparison that actually matters.

The verdict

For a US flyer picking one airline cobrand card in 2026, the answer depends on route pattern and existing card portfolio. United Explorer wins if you route through Newark, Chicago O'Hare, San Francisco, Houston, or Denver on United and want the flexibility of Star Alliance award redemptions with a low USD 95 annual fee. Delta SkyMiles Gold Amex wins if Atlanta, Seattle, Detroit, Minneapolis, or Salt Lake City is home and you value the annual USD 200 Delta flight credit and expanded free bag coverage across up to 8 companions. Southwest Rapid Rewards Priority wins if Dallas Love, Denver, Las Vegas, Chicago Midway, or Baltimore is home and you fly domestic short-haul frequently, with the added upside of Companion Pass eligibility. Do not carry all three unless you fly all three carriers meaningfully; the combined USD 394 annual fees only pencil out with heavy multi-carrier spend.

Where cobrand earn rate value comes from

Airline cobrand card value in 2026 breaks down across five levers, layered in order of practical impact on a mid-income flyer.

Lever 1: Category multipliers. United Explorer earns 2x on United purchases, 2x on dining including takeout and delivery, 2x on hotel stays booked directly with the hotel, and 1x elsewhere. Delta SkyMiles Gold Amex earns 2x on Delta purchases, 2x on restaurants worldwide including takeout and delivery, 2x on US supermarkets, and 1x elsewhere. Southwest Priority earns 3x on Southwest purchases, 2x on Rapid Rewards hotel and car partners, 2x on transit and rideshare, 2x on internet cable phone streaming, and 1x elsewhere. Delta Gold's US supermarket 2x is the standout non-airline category for a family budgeter; Southwest Priority's 3x on Southwest is the highest airline-direct multiplier.

Lever 2: Points valuation and redemption engine. United MileagePlus in 2026 values at roughly 1.2 to 1.4 cents per mile on Polaris business class redemptions through Star Alliance partners (ANA, Lufthansa, Turkish, Singapore), 1.1 to 1.3 on United-metal domestic. Delta SkyMiles values at 1.1 to 1.3 cents per mile with less transparent dynamic pricing; sweet spots exist on Virgin Atlantic partner awards to Europe and Air France KLM. Southwest Rapid Rewards is fixed formula, valued at 1.3 to 1.5 cents per point tied directly to cash fare, no fuel surcharges, cancel any time and points redeposit. Southwest's transparency wins for planners; United's Star Alliance wins for aspirational premium.

Lever 3: Annual fees and credits. United Explorer USD 95 (waived year one) plus USD 100 Global Entry or TSA PreCheck credit every 4 years, 25% back on inflight purchases, expanded award availability. Delta SkyMiles Gold Amex USD 150 (not waived) plus USD 200 Delta flight credit annually after USD 10,000 spend, 20% back on inflight purchases as statement credit, USD 100 resy credit annually. Southwest Priority USD 149 (not waived) plus USD 75 annual Southwest travel credit, 7,500 anniversary points, 4 upgraded boardings per year subject to availability. On effective annual fee net of credits, Southwest Priority runs highest (USD 149 minus USD 75 minus 7,500 points valued near USD 100 nets to negative) if you use both credits fully; Delta Gold matches at USD 150 minus USD 200 credit; United Explorer nets USD 95 with the least offsetting credit.

Lever 4: Free checked bags and companion benefits. United Explorer covers one free bag for cardholder plus one companion. Delta SkyMiles Gold covers one free bag for cardholder plus up to 8 companions on the same reservation. Southwest already offers two free bags to all Rapid Rewards flyers regardless of card. For a family of four flying Delta twice annually with checked bags, the SkyMiles Gold bag benefit is worth roughly USD 240 to 320 per year in avoided bag fees. For Southwest, the card adds no bag value.

Lever 5: Status and lounge access. None of the three grant airline elite status directly, though Delta Gold spending unlocks minor MQD (Medallion Qualifying Dollar) waivers with cardholder Reserve tier. None grant Sky Club, United Club, or premium lounge access; those require higher-tier cards (Delta Reserve, United Club Infinite, Chase Sapphire Reserve, Amex Platinum). If lounge is a priority, none of the three fits; consider stepping up to a premium card.

Layering the five levers: the "best" card is the one whose category multipliers, mile valuation, and credits align with your specific spend pattern and hub. Reference cards like Chase Sapphire Preferred and Capital One Venture X sometimes beat all three cobrand cards for pure earn rate on non-airline spend and offer transferable points to United, Delta partners, or Southwest respectively.

Modeled earn scenario: USD 25,000 annual card spend

For a typical mid-income flyer running roughly USD 25,000 through the primary card annually, split as USD 4,000 on the airline direct (2 domestic trips plus some ancillary purchases), USD 3,500 dining, USD 4,500 US supermarket, USD 2,000 transit rideshare, USD 11,000 other:

• United Explorer: 2x on USD 4,000 United + 2x on USD 3,500 dining + 1x on USD 4,500 grocery + 1x on USD 2,000 transit + 1x on USD 11,000 other = 8,000 + 7,000 + 4,500 + 2,000 + 11,000 = 32,500 miles annually. At 1.3 cents per mile valuation, USD 422 in mile value before credits.
• Delta SkyMiles Gold Amex: 2x on USD 4,000 Delta + 2x on USD 3,500 dining + 2x on USD 4,500 grocery + 1x on USD 2,000 transit + 1x on USD 11,000 other = 8,000 + 7,000 + 9,000 + 2,000 + 11,000 = 37,000 miles annually. At 1.2 cents per mile valuation, USD 444 in mile value before credits.
• Southwest Priority: 3x on USD 4,000 Southwest + 1x on USD 3,500 dining + 1x on USD 4,500 grocery + 2x on USD 2,000 transit + 2x on USD 3,000 (internet cable phone streaming subset of other) + 1x on USD 8,000 other = 12,000 + 3,500 + 4,500 + 4,000 + 6,000 + 8,000 = 38,000 points annually. At 1.4 cents per point valuation, USD 532 in point value before credits.

Net of annual fees and credits, Southwest Priority nets highest for the modeled flyer if they use the USD 75 travel credit and redeem the 7,500 anniversary points; Delta SkyMiles Gold nets second highest if they hit USD 10,000 to unlock the USD 200 credit; United Explorer nets third but has the lowest raw fee. Actual outcomes vary widely by spend mix.

How to pick

Flyer profile	Best pick	Why
Newark, Chicago O'Hare, San Francisco, Houston, or Denver based; flies United 2 to 6 times per year	United Explorer	Star Alliance award redemptions unlock premium cabin international value; USD 95 fee is the lowest of the three; free bag benefit for you plus one companion
Atlanta, Seattle, Detroit, Minneapolis, Salt Lake City based; family flyer	Delta SkyMiles Gold Amex	2x US supermarket helps grocery-heavy budget; USD 200 Delta credit after USD 10,000 spend often nets fee to zero or negative; free bag for up to 8 companions is family-friendly
Dallas Love, Denver, Chicago Midway, Baltimore, Las Vegas based; short-haul domestic frequent flyer	Southwest Priority	3x on Southwest is highest category earn; Companion Pass path is uniquely valuable; two free bags baseline
Already carry Chase Sapphire Preferred or Reserve	United Explorer	Chase UR transfers 1:1 to United, so Chase Sapphire already covers United earn; Explorer adds the free bag and priority boarding for one-off route needs
Already carry Amex Gold or Platinum	Delta SkyMiles Gold Amex	Amex MR transfers 1:1 to Delta; SkyMiles Gold's 2x grocery complements Gold's 4x grocery cap without overlap
Mixed carrier flyer (no single dominant hub)	Chase Sapphire Preferred (transferable) plus one cobrand	A transferable-points card gives redemption flexibility across United, Delta partners (via Virgin Atlantic), and Alaska (via Marriott); pair with one cobrand for status hooks
Rare flyer (under 2 flights per year)	Skip all three	Annual fees rarely offset for infrequent flyers; a no-annual-fee travel card like Wells Fargo Autograph or Bilt Mastercard is a better fit
Southwest Companion Pass hunter	Southwest Priority plus Southwest Premier or Performance	The Companion Pass requires 135,000 Rapid Rewards points in a calendar year; stacking two Southwest cobrand sign-up bonuses is the standard path
Business owner with heavy travel	United Club Business, Delta Reserve Business, or Southwest Performance Business	Business versions of the same cards add lounge access, higher category caps, and pass expensing through the business rather than personal
International premium cabin aspirant	United Explorer as gateway to Chase UR ecosystem	The Explorer alone earns United miles slowly; using the Explorer while spending heavily on Chase Sapphire and Chase Ink for UR points builds Star Alliance premium redemption capacity

The single biggest mistake mid-income flyers make with cobrand cards is carrying two or three with overlapping annual fees while flying only one carrier meaningfully. Pick the card that matches your dominant carrier, and add a Chase or Amex transferable points card as your everyday earner.

United Explorer callout

The United Explorer Card sits as the low-fee entry to United MileagePlus in 2026. USD 95 annual fee (waived first year), 2x on United purchases, 2x on dining including takeout and delivery, 2x on hotels booked direct, 1x elsewhere. Benefits: one free checked bag for primary cardholder and one companion, priority boarding, 25% back on United inflight purchases as statement credit, USD 100 Global Entry or TSA PreCheck credit every 4 years, expanded award availability on United-metal flights (Saver seats not otherwise released). Foreign transaction fee 0%. Star Alliance transfers unlock the highest redemption ceiling of the three cards through partners like ANA, Lufthansa, Turkish, and Singapore. Chase UR transfers 1:1 to United MileagePlus, meaning any Chase Sapphire Preferred or Chase Ink Business Preferred holder can already accumulate United miles at a higher earn rate than the Explorer offers. Best fit: United hub-city flyer who wants free bags and priority boarding without stepping up to United Club Infinite at USD 525 annually.

Delta SkyMiles Gold American Express callout

Delta SkyMiles Gold American Express is the mid-fee family card for Delta hub-city flyers in 2026. USD 150 annual fee (not waived), 2x on Delta purchases, 2x on restaurants worldwide including takeout, 2x on US supermarkets, 1x elsewhere. Benefits: one free checked bag for primary cardholder and up to 8 companions on the same reservation, priority boarding on Delta, 20% back on Delta inflight purchases, USD 200 Delta flight credit annually after USD 10,000 spend, USD 100 resy credit annually. Foreign transaction fee 0%. Amex MR transfers 1:1 to Delta SkyMiles for Gold, Platinum, and Green cardholders, so heavy Amex ecosystem users already have a fast SkyMiles path. Delta's dynamic redemption pricing means the 2x airline earn value fluctuates; sweet spots exist on Virgin Atlantic partner awards to Europe (roughly 47,500 miles one-way business class New York to London on select dates) and Air France KLM redemptions. Best fit: Atlanta, Seattle, Detroit, or Minneapolis based flyer with grocery-heavy household spend and 1 to 3 Delta trips per year.

Southwest Rapid Rewards Priority callout

Southwest Rapid Rewards Priority is the top-tier consumer Southwest card in 2026. USD 149 annual fee (not waived), 3x on Southwest purchases, 2x on Rapid Rewards hotel and car partners, 2x on internet cable phone streaming, 2x on transit and rideshare, 1x elsewhere. Benefits: USD 75 annual Southwest travel credit, 7,500 anniversary points, 4 upgraded boardings per year subject to availability, 25% back on inflight drinks and Wi-Fi. Foreign transaction fee 0%. Southwest already offers two free checked bags to all Rapid Rewards flyers regardless of card, so the card does not add a bag benefit. Southwest Rapid Rewards has no external transfer partners, meaning points earned must come from direct Southwest flying or Southwest cobrand cards; this constrains the earn ceiling relative to United and Delta. Companion Pass eligibility (135,000 points in a calendar year, or 100 flight segments) is the reason to stack Priority with a Southwest Premier or Performance Business card early in a calendar year. Best fit: Dallas Love, Chicago Midway, Denver, Las Vegas, or Baltimore based short-haul domestic flyer targeting Companion Pass.

Chase UR and Amex MR context callout

Neither Chase Ultimate Rewards nor Amex Membership Rewards is airline-specific, but both change the cobrand calculus. Chase UR transfers 1:1 to United MileagePlus, Southwest Rapid Rewards, Air France KLM Flying Blue (a Delta partner sometimes cheaper for European redemptions), Iberia Avios (which redeems at British Airways rates on Oneworld), and 11 other partners. Amex MR transfers 1:1 to Delta SkyMiles, Air France KLM Flying Blue, Air Canada Aeroplan (Star Alliance partner useful for United awards), ANA (Star Alliance premium), and roughly 20 total partners. If you already carry Chase Sapphire Preferred or Reserve, or Amex Gold or Platinum, the cobrand card becomes primarily a benefits play (free bags, priority boarding, credits) rather than a pure earn play, because the transferable-points card earns bonused categories at higher rates and gives redemption flexibility across multiple airlines.

What this means in practice

In practice, a Newark based flyer taking two round-trip United flights to San Francisco per year, one to Frankfurt on Lufthansa Business (a Star Alliance partner), spending USD 4,000 on United purchases, USD 3,500 on dining, USD 4,500 on US groceries, USD 2,000 on transit rideshare, and USD 11,000 on other categories, earns 32,500 United miles annually on the Explorer, worth roughly USD 400 to USD 500 in Star Alliance business class redemptions. Combined with the USD 95 annual fee (waived year one), the USD 100 Global Entry credit prorated to USD 25 per year, and the free checked bag benefit on two annual round-trips (roughly USD 140 saved), the net value sits around USD 450 to 550 in year one and USD 350 to 450 in subsequent years.

The same modeled Atlanta based flyer on Delta SkyMiles Gold Amex earns 37,000 SkyMiles worth roughly USD 400 to USD 480, plus the USD 200 Delta flight credit (net USD 50 annual fee), the free checked bag benefit for the flyer plus family of three (roughly USD 240 saved), USD 100 resy credit, USD 100 rideshare Uber credit. Net value in the USD 500 to 700 range for a family flyer.

The Dallas based Southwest flyer on Priority earns 38,000 Rapid Rewards points worth roughly USD 480 to USD 570 cash-fare value, plus the USD 75 Southwest credit, 7,500 anniversary points worth roughly USD 100, and access to Companion Pass paths. Net value in the USD 500 to 700 range for a short-haul domestic flyer.

Across all three: use the ShopBack browser extension to activate cashback when booking flights and hotels via participating merchants; the extension layers on top of miles earned. Cross-check hotel booking prices for award-companion cash stays via the ShopBack Travel Planner, which cross-references Booking.com, Expedia, Hotels.com, and Agoda for United, Delta, and Southwest destinations in a single search. On the finance side, the ShopBack US finance vertical publishes ongoing updates to travel credit card comparisons so you can rebalance card portfolios when issuers refresh benefits.

When this does NOT apply

• You revolve balances monthly. Cobrand credit card interest rates in 2026 run 21 to 30% APR, well above miles value earned. If you carry a balance, focus on a low-APR balance transfer card first; airline cobrand math only works with pay-in-full behavior.
• Southwest departure from a non-hub city. Southwest's schedule is uneven across smaller markets, and cash fares from smaller airports often rival or beat Rapid Rewards redemptions. Priority is only worthwhile if you fly Southwest regularly on routes with meaningful cash-fare advantage.
• Delta MQD earning is your goal. SkyMiles Gold Amex does not accelerate Medallion Qualifying Dollar earning meaningfully; that requires Delta SkyMiles Platinum (USD 350 fee) or Reserve (USD 650 fee). If Delta Medallion status is the target, step up.
• International long-haul non-Star Alliance flyer. If your international travel routes through Oneworld (American, British Airways, Cathay, Qatar) or SkyTeam (Delta, Air France, KLM, Korean Air), United Explorer's Star Alliance transfers do not help; consider the Citi AAdvantage Executive or Delta SkyMiles Platinum instead.
• You already hold Chase Sapphire Reserve and Amex Platinum. The USD 550 and USD 695 premium cards cover priority boarding equivalents through Chase Sapphire Lounge access or Amex Centurion, free bags via partner benefits, and 3x to 5x on airlines direct. Adding a cobrand card creates fee overlap without proportional benefit gain.
• You do not clear the sign-up bonus minimum spend. Sign-up bonuses represent 40 to 70% of first-year value for cobrand cards. If you cannot hit the USD 3,000 in 3 months (or equivalent) organically, the card is less compelling in the first 12 months.
• Your work reimburses travel. Card benefits like free bags and priority boarding matter less when the employer covers those regardless. Focus on transferable points for personal travel redemption instead.

Frequently asked questions

Which airline cobrand card has the highest earn rate on airline-direct spend in 2026?

Delta SkyMiles Gold American Express earns 2 miles per dollar on Delta purchases, matched by Southwest Rapid Rewards Priority at 3 points per dollar on Southwest purchases, and United Explorer at 2 miles per dollar on United purchases. Adjusted for typical cent-per-mile valuations (Delta SkyMiles at 1.1 to 1.3 cents, Southwest Rapid Rewards at 1.3 to 1.5 cents, United MileagePlus at 1.2 to 1.4 cents), Southwest Priority effectively wins on airline-direct spend for domestic short-haul flyers, and United Explorer wins for international long-haul redemptions.

What is the annual fee difference between United Explorer, Delta SkyMiles Gold, and Southwest Priority?

As of 2026-08-27, United Explorer charges USD 95 annually (waived first year), Delta SkyMiles Gold American Express charges USD 150 annually (no first-year waiver on current offer), and Southwest Rapid Rewards Priority charges USD 149 annually with no first-year waiver. All three include recurring credits: United Explorer offers a USD 100 Global Entry or TSA PreCheck statement credit every 4 years, Delta Gold offers a USD 200 Delta flight credit annually after USD 10,000 spend, and Southwest Priority offers a USD 75 Southwest travel credit annually plus 7,500 anniversary points.

How does the CFPB 2025 credit card report describe cobrand cardholders?

The CFPB's October 2025 Consumer Credit Card Market Report notes that airline cobrand cardholders skew higher-income than the average general-purpose cardholder, though a substantial majority still earn under USD 100,000 annually. The report also highlights that cobrand card users are more likely to revolve balances during high-spend travel months, which erodes miles value against interest charged. Practical implication for US flyers: only optimize earn rate if you pay in full monthly.

Compare sign-up bonuses across United Explorer, Delta SkyMiles Gold, and Southwest Priority in 2026

Sign-up bonuses fluctuate monthly, but as of 2026-08-27, publicly listed offers on issuer sites are: United Explorer 60,000 miles after USD 3,000 spend in 3 months; Delta SkyMiles Gold Amex 65,000 miles after USD 3,000 spend in 6 months; Southwest Priority 50,000 points after USD 1,000 spend in 3 months. Elevated targeted offers (75,000 to 100,000 miles) rotate through referral links and airline promo periods for all three; verify current terms on united.com, americanexpress.com, and chase.com before applying.

Does the Southwest Companion Pass require a specific credit card?

No specific card is required, but the Companion Pass requires 135,000 Rapid Rewards points earned in a calendar year (as of 2026, up from prior thresholds) or 100 flight segments. Points earned from Southwest cobrand cards (Plus, Premier, Priority, Performance Business) count toward the qualifying total. Southwest Priority's 3x on Southwest, 2x on transit and internet cable phone, and 1x elsewhere can move a heavy Southwest flyer toward the pass, but a solo Priority card alone rarely gets you there without sign-up bonus stacking or heavy Southwest spend.

Are United MileagePlus miles more valuable than Delta SkyMiles or Southwest Rapid Rewards in 2026?

In 2026, points valuations from major travel-award publishers place United MileagePlus at roughly 1.2 to 1.4 cents per mile (highest value on Polaris business award redemptions through Star Alliance partners), Delta SkyMiles at 1.1 to 1.3 cents per mile (harder to unlock high value due to dynamic pricing), and Southwest Rapid Rewards at 1.3 to 1.5 cents per point (transparent fixed formula tied to cash fare). These valuations shift as programs devalue; verify against fresh published points valuations on TPG, One Mile at a Time, or Frequent Miler before making a redemption decision.

Why do the free checked bag benefits differ on each card?

United Explorer gives one free checked bag for the primary cardmember and one companion on the same reservation. Delta SkyMiles Gold Amex gives one free checked bag for the primary cardmember and up to 8 companions on the same reservation, subject to Delta's terms. Southwest already includes two free checked bags for all Rapid Rewards flyers regardless of card, so the Priority card does not add a bag benefit beyond baseline. For a family of four flying United or Delta twice a year, the bag benefit alone can offset the annual fee.

Can I combine points from these cards with a Chase Sapphire or Amex Gold?

United MileagePlus receives 1:1 transfers from Chase Ultimate Rewards (Chase Sapphire Preferred, Reserve, or Ink Business Preferred hold transfer eligibility). Delta SkyMiles receives 1:1 transfers from American Express Membership Rewards (Amex Gold, Platinum, Green, and Business Platinum). Southwest Rapid Rewards does not receive external transfer partners; points must be earned directly through flying or Southwest cobrand cards. If you carry a Chase Sapphire or Amex Gold as your everyday card, the cobrand becomes primarily a status and benefits play rather than a pure earn play.

Would ShopBack help me maximize airline cobrand card value in 2026?

The ShopBack browser extension automatically activates cashback at checkout on participating US airline booking sites and travel merchants, layering on top of miles earned via cobrand cards for a stackable saving. The ShopBack Travel Planner at shopback.com/travel cross-checks live cash-fare prices across Booking.com, Expedia, and Hotels.com for hotel award-nights companion bookings and paired trip stays, so you can validate whether a miles redemption or a cash fare wins on a specific route. Both tools live within a single ShopBack account and require no separate activation beyond initial signup.

Should I get all three cards or pick one?

Pick the cobrand card matched to your dominant airline hub and flying pattern. A New York or Newark based flyer routing through United's Newark hub picks Explorer. An Atlanta, Seattle, Detroit, or Minneapolis based flyer routing through Delta hubs picks SkyMiles Gold. A Southwest heavy short-haul flyer based in Dallas, Denver, Las Vegas, Baltimore, or Chicago Midway picks Priority. Carrying all three costs USD 394 annually in fees; the math only works if you fly all three carriers enough to redeem the credits and earn category multipliers meaningfully across each.
