Find your next flight deal

Everyone loves a cheap flight—but finding one? That’s where Priceline comes in. Whether you’re flying across the country or around the world, we help travelers uncover serious savings with powerful tools, flexible options, and deals you won’t see anywhere else. With a few strategic tips (and a little timing), your next trip can take off for less!!

Flying out on a Thursday, Friday, or Saturday is your best bet for saving on domestic airfare—potentially up to 12% compared to peak departure days. For international flights, Thursday takes the crown for cheapest day to fly, while Sundays tend to carry the highest price tags.

Timing your return flight matters just as much as your departure. Fridays and Saturdays are typically the most expensive days to fly home. Want to save? Aim for a Monday return, which can trim as much as 12% off your fare—both for domestic and international routes.

Yes—and here’s a big one: departing on a Saturday and returning on a Tuesday often offers the cheapest round-trip pricing. If your travel dates are flexible, this combo can save you up to 30% on airfare.

For domestic U.S. travel, September is typically the cheapest month to fly, followed closely by February. The most expensive months? December, March, and June—thanks to holiday travel and spring/summer vacations. International flights follow a similar trend: February and March offer the best deals, while December is the priciest. Returning in January can also be costly due to post-holiday demand.

This travel hack has mostly been debunked in recent years, but there may be some small price fluctuations during the week. For domestic U.S. flights, booking on Saturdays or Sundays can save you 2–3% compared to peak booking days. Prices tend to climb on Mondays, when demand picks back up. For international trips, mid-week is your money-saving window—Tuesdays often bring the lowest prices, with fares increasing steadily toward the weekend, although, again, it isn’t enough to call it a travel hack.

Speaking of travel hacks, start with Express Deals.  Think of these deeply discounted fares as mystery deals. You choose the general flight time and destination and we share potential airlines and number of stops. In exchange for up to 50% off retail fares, we only reveal the exact details after booking. It’s a great way to unlock major savings if you’re flexible. You can sort or search specifically for Express Deals to zero in on the best offers.

Try an Express Deal or let Priceline help you build a custom itinerary that works for your budget. Booking two one-way flights on different airlines can result in cheaper round trips, and we make it easy. Our deals engine will automatically suggest the best roundtrip options while mixing and matching airlines.

If you're traveling within the U.S., flight prices typically begin increasing 3–4 weeks before departure, then rise quickly from there. Need to book closer to takeoff? Try Priceline’s Express Deals, or bundle your flight with a hotel or rental car to tap into package pricing—often a hidden gem for late planners. For international trips to Europe, prices start rising about 2 weeks out—so don't wait too long.

Priceline brings a lot more to the table than just booking flights. We work directly with the top travel brands to secure significant discounts on domestic and international travel, so customers don’t need to shop around for the best prices. We also offer exclusive Express Deals that beat retail rates, a deals engine  that automatically builds round trip itineraries using one way tickets providing more routes and rates, and the ability to bundle hotels, rental cars, cruises, and even travel insurance—all in one place. Plus, with our Priceline VIP program, the more you book, the more perks and discounts you unlock – while also still earning your airline’s frequent flier miles. It’s travel made smarter, and cheaper.

And, when you book with Priceline, you have the added benefit of having us act as your advocate if something goes wrong. If you encounter an issue or you’re not satisfied with your experience, Priceline will help file complaints, compensation requests and submit documentation to be considered for policy exemptions.
