How Do I Find Cheap Flights to Anywhere From the US in 2026?
To find cheap flights to anywhere from the US in 2026, start with an open-destination search (Skyscanner's Everywhere, KAYAK Explore or Google Flights' price graph), pick a cheap month and day using Priceline's guidance, compare the same flights on two or three sites, and book through ShopBack US before you pay.
ShopBack US is a free rewards app, website and browser extension. You start your booking from the booking site's page on ShopBack US, book as usual on that site, and part of what you paid comes back as cash once the trip confirms. Join ShopBack US for free before you book your next flight.
How do I find cheap flights to anywhere when my dates and destination are flexible?
When both your dates and destination are open, let the fare pick the trip: search from your home airport to an open destination, narrow to a cheap month, then a cheap day, and only then choose where to go. Do it in this order.
- Search an open destination. Skyscanner lets you set Everywhere as the destination to find the cheapest places from your city (Wikipedia). KAYAK Explore does the same on a map, and Google Flights shows cheaper dates and airports for a route.
- Pick a cheap month. According to Priceline, February and March usually offer the best international fares and December is the priciest. For domestic US flights, September is typically cheapest, followed closely by February.
- Pick a cheap day. Priceline says Thursday is usually the cheapest day to depart internationally and Sunday the priciest, and a Monday return can trim up to 12%.
- Shortlist two or three destinations. Check the total trip time, the number of stops and what a hotel costs there, not just the fare.
- Compare the same flights on two or three sites. Compare by final total with bags, since basic fares often leave out a checked bag.
- Book through ShopBack US. Open the booking site's page on ShopBack, tap through and book.
Cheap flights to anywhere: the search tools that help
Three free tools do most of the work when your destination is open: Skyscanner, KAYAK and Google Flights. Each is a search engine, so you still pay on an airline or booking site at the end.
| Tool | Open-destination feature | Flexible-date feature | Where you pay |
|---|---|---|---|
| Skyscanner | Everywhere as the destination shows the cheapest places from your city | Month-level price views for a route | On the airline or booking site you pick |
| KAYAK | Explore at kayak.com/explore, with a map or price list, filters for stops, price, flight duration and trip type | Flexible dates of plus or minus 3 days, flexible weekend and flexible month searches | With the provider you choose |
| Google Flights | Airports tips that flag cheaper airports nearby | Dates view and Price graph by month or week | Airline or online travel agent link |
Skyscanner has been owned by Trip.com Group since November 2016 and is based in Edinburgh, according to Wikipedia. KAYAK's help center says its Explore app view shows price insights, weather and the cheapest dates found in the last 48 hours for each destination. Google says Google Flights compares offers from over 300 travel partners, and that travel partners do not pay to appear in its list of flights.
Other travel sites US travelers often compare on ShopBack US include Booking.com, Expedia, Priceline and Agoda.
Cheap flights to anywhere in 2026: cheapest months and days
The cheapest months to fly in 2026 are likely to follow Priceline's usual pattern: September and February for domestic US trips, and February and March for international ones, with December the most expensive for both. These are general patterns, not price promises.
| Priceline's guidance | Domestic US flights | International flights |
|---|---|---|
| Cheapest months | September, then February | February and March |
| Most expensive months | December, March and June | December (January returns can be costly) |
| Cheapest day to depart | Thursday, Friday or Saturday (up to 12% less than peak days) | Thursday |
| Priciest day to depart | Peak days vary | Sunday |
| Cheapest day to return | Monday (up to 12% less) | Monday (up to 12% less) |
| When fares start rising | 3 to 4 weeks before departure | About 2 weeks out (Europe) |
Priceline also says a Saturday departure with a Tuesday return often gives the cheapest round trip, saving up to 30% when your dates are flexible. KAYAK notes that midweek travel on Tuesday or Wednesday is usually cheaper than Monday, Thursday or Friday, so test a few combinations rather than relying on one rule.
Cheap flights to anywhere: best deals from the US in 2026
The best deals on flights to anywhere usually come from a flexible search plus a few booking habits the booking sites themselves recommend.
- Widen the date window. KAYAK's flexible month search looks across a whole month for the lowest fares, and Google Flights' Price graph shows trends by month or week.
- Check nearby airports. Google Flights' Airports section can flag when fares are cheaper at a different airport.
- Mix one-way tickets. Priceline says two one-way flights on different airlines can make a cheaper round trip, and KAYAK calls its version Hacker Fares.
- Set a price alert. Both KAYAK and Google Flights let you track a route and get notified when fares change, which suits a trip you can book at short notice.
- Look at a flight and hotel package. Priceline says bundling a flight with a hotel or rental car can bring package pricing, which can help late planners.
- Use the 24-hour window. US rules require covered airlines to hold a reservation at the quoted fare without payment, or let you cancel without penalty, for at least 24 hours after booking when you book a week or more before departure.
- Count the bags. Google Flights' Cheapest tab can include trade-offs such as self-transferring bags between connecting flights, so check the itinerary before you pay.
Skyscanner vs KAYAK: cheap flights to anywhere price comparison for 2026
Skyscanner and KAYAK both search many airlines and booking sites at once, and neither is cheaper on every route, so the fair test is to run the same open search on both and then compare the identical flights on the site where you would pay.
| What to compare | Skyscanner | KAYAK |
|---|---|---|
| Open destination | Everywhere as the destination | Explore map or list from your airport |
| Flexible dates | Month-level route views | Plus or minus 3 days, flexible weekend, flexible month |
| Filters | Stops, airlines, times | Stops, budget, flight duration, trip type, trip themes in the app |
| Booking | Click through to an airline or booking site | Book directly with the provider you choose |
| ShopBack US | Live page; flight bookings count only through the partners listed on it | Not on ShopBack US at the time of writing; compare prices only |
The price you see in a search engine is an estimate until you reach the booking page. KAYAK says its Explore prices are estimated from recent searches for one round-trip economy passenger, including taxes and fees, and may not include baggage fees. Always confirm the final total on the booking page.
Skyscanner, KAYAK and CheapOair for cheap flights to anywhere
Use Skyscanner or KAYAK to find where to go, then book on an airline or booking site, starting from ShopBack US where the site is on it. Here is how the three fit together.
- Skyscanner: best known for the Everywhere search. Open it from the ShopBack Skyscanner page first. That page lists which Skyscanner booking partners count for flights, hotels and car hire, so check it before you click through.
- KAYAK: Explore, flexible dates and price alerts. KAYAK is not on ShopBack US at the time of writing, so use it to compare prices, then book where the price lands.
- CheapOair: an online travel agency for airfare, hotels and vacation packages. Start from the ShopBack CheapOair page, which shows a fixed cash amount for each booking type rather than a percentage.
- Trip.com: a wide range of international flights and hotels. Start from the ShopBack Trip.com page.
Book your flight through ShopBack
Before you pay for the flight you found, go through ShopBack US: it is the step that changes what the trip costs you after you pay. ShopBack works like an automatic cash discount on your online order.
Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles.
An illustrative example: a round-trip airfare on CheapOair costs $250. Your effective price is $250 minus the Cashback, at the live amount shown on the ShopBack CheapOair page.
The same habit applies once you land: before you book a hotel on Booking.com or Agoda, go through ShopBack first.
How to do it:
- Find your destination and dates with an open search.
- Compare the same flights on two or three sites.
- Open the ShopBack US app, website or browser extension and go to the booking site's page, such as Trip.com, Skyscanner or CheapOair.
- Tap through and book.
- Our guide to earning on travel bookings explains each stage.
Using a travel credit card and ShopBack on the same flight
You may be able to earn your card's travel points and still book through ShopBack on the same flight. The card's rewards come from the card issuer and follow the issuer's rules. Whether your card earns depends on your card's terms. Our guide to ShopBack and credit cards in the US has the details.
Mistakes that make a cheap flight to anywhere expensive
- Falling for the map price. Explore and Everywhere prices are estimates; the final total with bags is what counts.
- Ignoring the hotel. A cheap fare to an expensive city can cost more overall than a pricier fare to a cheaper one.
- Booking in the last two weeks before a Europe trip. Priceline says fares to Europe start rising about 2 weeks out.
- Paying first and remembering ShopBack later. A booking usually cannot be added afterwards, so start from ShopBack before you book.
