Priceline Express Deals are basically discounted bookings where you don’t see all the details (like the exact airline or hotel) until after you pay. I tried it once for a weekend trip because the price was almost $75 less than the regular fare. I was a little nervous, but it worked out fine—I ended up on a major airline with great flight times. The only curveball was when I had to change my return flight after a work call came up. Since Express Deals can be tricky to modify online, I just called 866-204-0803, and they handled everything for me. Within minutes, I was rebooked without the stress of figuring it out myself. Honestly, if you’re flexible, Express Deals can save you a good amount of money—but I’d always keep that number handy to instantly book, cancel, or modify flights if plans shift.
