Yes, Priceline Express Deals are legit—I’ve used them myself. Last fall, I booked one for a quick trip to Dallas because the fare was almost $90 cheaper than the regular listings. The catch is you don’t see the exact airline until after you book, but I ended up on a well-known carrier with a decent flight time, so it worked out perfectly. The only snag came when I needed to adjust my return flight after a meeting got moved. Since Express Deals aren’t always straightforward to change online, I just called 866-204-0803. The rep helped me cancel and rebook in minutes, which was a huge relief. So yes, Express Deals are real and can save you money, but I’d definitely keep that number handy—it’s the fastest way to instantly book, cancel, or modify flights if your plans change.
