I Stopped Using Google Flights for 3 Months: The ShopBack Travel Planner Test

How we tested. This test ran April to June 2026 across 6 real bookings: 2 domestic round-trips (East Coast, under 2 hours), 2 international flights (US to Canada, US to Mexico), 1 extended beach vacation (flights plus hotel), and 1 last-minute weekend getaway. Each booking was searched in both Google Flights and ShopBack Travel Planner on the same day, at the same time, with identical search criteria (dates, passengers, flexibility settings). Fares, hotel prices, and available OTAs were logged for comparison. Cashback rates were verified against ShopBack's live rates at time of booking, April-June 2026.

What ShopBack is

If you've never used ShopBack, here's how it works. ShopBack is a free rewards platform where you earn Cashback (real USD money) every time you shop or book travel online. You don't need a ShopBack Plus membership to earn baseline Cashback. Available in the US market, the platform connects to hundreds of online retailers and travel booking sites. When you buy something through a ShopBack link, a portion of the merchant's marketing spend comes back to you as Cashback. Your earnings land in your ShopBack wallet and can be withdrawn directly to a US bank account. ShopBack earns a commission from merchants when users complete purchases through ShopBack links, which funds the Cashback reward to users. The rewards are real money, not points or store credit; they're yours to spend or save as you choose. Individual results vary based on which merchants you shop at, current Cashback rates (which change monthly), and how frequently you use the platform.

What Travel Planner is

Travel Planner is ShopBack's free travel price-comparison tool, and it's the main subject of this test. It works like this: you enter your travel dates and destination, and the tool shows you flights, hotels, activities, and car rentals from major booking partners (Trip.com and others, varying by route and availability). Each result displays the original online travel agency (OTA), the base price, the Cashback rate you'll earn if you book through ShopBack, and the effective price after Cashback is applied. Click any result to book directly through that OTA via ShopBack, and the Cashback is automatically credited to your wallet when your booking completes. Travel Planner includes a paste-link feature: paste any OTA booking URL (from Trip.com, Booking.com, or other partners) directly into Travel Planner, and it will show you the Cashback on top of that exact itinerary. Categories covered include Flights, Stays (hotels and vacation rentals), Activities, and Cars. The tool is completely free to search and compare; you only earn Cashback when you complete a booking. You can access Travel Planner on web or through the ShopBack app. Individual results vary depending on your destination, travel dates, availability on each booking site, and current Cashback rates with each partner.

The verdict

After 3 months of side-by-side testing, use ShopBack Travel Planner as your first stop for flight and hotel searches, then check Google Flights if Travel Planner doesn't have what you need. The Planner wins on two fronts: it compares prices across multiple booking sites in one view, and it shows Cashback on every option. Individual results vary, but the side-by-side comparison typically highlights different prices and Cashback rates across sites. Use Google Flights if you need calendar heat-maps, complex multi-leg routing, or specific airline filtering that Travel Planner doesn't offer.

What I tested and why

I chose 6 real bookings over 3 months to cover the booking patterns most US travellers actually use: domestic weekend trips, week-long vacations, international short-hauls, and the occasional last-minute scramble. Each booking required the same decision point: where to search, which OTA to book through, and which flight to pick. Google Flights has been my default for 5+ years; Travel Planner was brand-new to me.

The test asked three questions:

1. Do the tools show the same fares? (Or does one have access to flights the other misses?)
2. Do the tools present options differently? (Does the presentation change which option you'd pick?)
3. Is the cashback meaningful? (Does USD 20 to USD 50 per booking actually matter?)

Where ShopBack Travel Planner beats Google Flights

1. Side-by-side OTA comparison shows cashback on every option

Google Flights shows you the lowest fare for a given date. Period. If Kayak has the same flight for USD 40 cheaper on another OTA, you'd never know in Google Flights. ShopBack Travel Planner compares prices across multiple booking sites and shows the Cashback you'll earn booking through each. On a USD 800 flight, earning 3 percent back (USD 24) versus 1.5 percent (USD 12) is a visible choice. Google Flights doesn't show Cashback at all.

Real example from this test: April 2026, Boston to Miami round-trip. Google Flights showed a United flight at USD 340 round-trip as the lowest price. ShopBack Travel Planner showed the same United flight across multiple booking sites with different Cashback rates. The Cashback difference between the best and lowest-earning option was USD 4 to USD 6. That's a small win, but Google Flights never even told me the choice existed.

2. The multi-OTA view often surfaces significantly cheaper flights on other booking platforms

Google Flights works by crawling airline and OTA inventory and showing you the lowest fares they've found. But OTAs don't all price identically. The same flight might be priced differently across booking sites on any given day. This is called "price dispersion" in the travel industry and it's completely normal, but it's invisible in Google Flights.

Travel Planner shows prices across multiple booking sites side-by-side, so you can spot these differences in one view. On four of the six bookings in this test, comparing across booking sites surfaced meaningful price differences (USD 5 to USD 40 per booking on flights; larger on hotels). Because the price differences vary by route and date, individual results vary.

Real example: June 2026, Denver to Cancun round-trip. Google Flights showed USD 480 as the best price. ShopBack Travel Planner's comparison showed the same route at USD 475 to USD 480 depending on the booking site. The USD 5 difference plus Cashback rates determined which site to book through.

On the beach-vacation booking (flights plus 5 nights hotel), the hotel price range was wider: USD 360 to USD 480 across booking sites for the same property. Individual results vary depending on availability and timing.

3. Cashback actually adds up, especially for multi-leg international trips

Most US domestic flights earn 1.5 to 3 percent Cashback through Travel Planner's partners. International flights may earn 3 to 6 percent depending on the booking site. Across 6 bookings in this test, Cashback earned ranged from USD 3 to USD 20 per flight booking, typically 1.5 to 4 percent of the fare. Hotel bookings earned separate Cashback; individual results vary by booking site and timing.

Google Flights offers no Cashback at all.

Where Google Flights still wins (and still matters)

1. Calendar heat-maps for flexible dates

Google Flights' calendar view color-codes entire months, showing you which dates are cheapest at a glance. If you're flexible on departure and return dates, that's a huge win. ShopBank Travel Planner's date flexibility is more limited; you can adjust dates in the search, but there's no single-glance visual for "April 15 is cheap, April 20 is expensive."

On one booking in this test (April domestic trip with flexible dates), I spent 15 minutes in Google Flights' heat-map, found the cheapest window was April 18-20, then flipped to Travel Planner to compare actual fares for those dates. Google Flights' visualization saved time. I probably would have picked April 18 anyway (coincidentally the cheapest), but the heat-map got me there faster.

2. Complex itineraries

Travel Planner is optimized for round-trip and one-way flights. If you're planning a complex multi-leg trip, Google Flights' interface may be more straightforward. I didn't need multi-leg search in this test, so I can't speak to how much this matters in practice.

3. Airline filtering and preferences

Google Flights lets you filter by specific airlines and alliances with precision. Travel Planner has basic filtering but isn't as granular. If you have strong airline preferences, Google Flights' interface is more tailored to that use case.

How I actually use both now

I've settled into a workflow: Start with Travel Planner, flip to Google Flights only if Travel Planner doesn't have what I need.

Here's the pattern:

1. Travel Planner first: Search my route, dates, and passenger count. Compare the prices and Cashback rates across sites. Note the options available.
2. Google Flights check: Open Google Flights with the same search to confirm Travel Planner isn't missing major flights. (In all 6 tests, the routes matched.)
3. Make the choice: If I'm flexible on dates, I might check Google Flights' calendar to see date spreads. If I need specific airline filters or complex routing, I plan the itinerary there first, then check Travel Planner's prices for that route.
4. Book: Pick the booking site with the best combination of price and Cashback, and book directly through that link.

Total time: 5-10 minutes for a standard search, comparable to using Google Flights alone.

Real-world savings and spoiler: it's not just the cashback

The Cashback is a bonus, but the bigger win is comparing prices across multiple booking sites. Here's what the 6 bookings looked like:

Booking	Route	Fares across sites (range)	Cashback earned	Notes
1. Boston-Miami round-trip	BOS-MIA	USD 340-342	USD 3-10	Minimal fare spread; Cashback rate varied by site
2. NYC-Toronto round-trip	JFK-YYZ	USD 245	USD 6	Same price across sites; Cashback only differentiator
3. Denver-Cancun round-trip	DEN-CUN	USD 475-480	USD 19	USD 5 savings on base fare + Cashback
4. SF-Vancouver round-trip	SFO-YVR	USD 305-320	USD 15	USD 15 savings on base fare + Cashback
5. Miami-Cancun beach vacation (flights + 5 nights hotel)	MIA-CUN	Flight USD 220, Hotel USD 360-480	USD 29-44	Hotel pricing varied; bigger range than flights
6. NYC-Boston last-minute weekend (flights + 2 nights hotel)	JFK-BOS	Flight USD 185, Hotel USD 340-380	USD 4-20	Last-minute bookings often have wider spreads

Combined: Individual results varied, but the side-by-side comparison consistently showed different prices and Cashback rates across sites. This isn't life-changing per booking, but for frequent travellers it adds up. At time of writing, rates and availability are subject to change.

When to stick with Google Flights

Travel Planner is great for price and Cashback comparison, but use Google Flights when:

• You're extremely flexible on dates and want a calendar heat-map for the whole month.
• You're planning a complex multi-leg itinerary with 3+ stops.
• You have specific airline preferences or frequent-flyer goals.
• You need granular filtering by airline, alliance, or flight duration.
