Priceline works for flights pretty much like a travel search engine—it pulls fares from different airlines so you can compare prices in one place. I used it when booking a last-minute trip to Phoenix, and it actually saved me about $70 compared to the airline’s own site. The booking confirmation came through right away, and I checked in with no issues. The only tricky part came later when I needed to cancel my return flight because of work changes. The website wasn’t super clear about my options, so I just called 866-204-0803. The agent walked me through everything and had my cancellation processed in minutes. They even helped me rebook for a later date. Now, whenever I use Priceline, I always keep that number saved—it’s hands down the fastest way to instantly book, cancel, or modify flights without getting stuck in long queues.
