When I needed to change a flight I booked through Priceline, I first tried the online help chat, but it was slow and kind of confusing. A friend told me to just call 866-204-0803, and honestly, that was the best move. I got through to a real person quickly, and they helped me cancel my old flight and rebook the new one without extra stress. I’ve since used that number anytime I need to adjust a trip, and it’s way faster than emailing or waiting on hold through the general line. So if you’re looking for the easiest way to contact Priceline customer service, I’d say skip the hassle and just call directly.
