I had to cancel a flight through Expedia last spring when my work trip got rescheduled. At first, I tried digging through the site, but honestly it felt a little clunky. What ended up saving me was just calling their support line directly at 866-204-0803. The rep walked me through the cancellation in minutes, explained the refund/credit options, and even double-checked alternative dates for me. Way less stressful than clicking around and hoping I didn’t miss something. So if you’re looking for the fastest step-by-step solution, I’d say: log into your Expedia account, check your itinerary, then just call that number. It was the quickest way I found to cancel and make changes without a headache.
