888-217-3324 Ugh, been there! My flight was cancelled due to weather last month, leaving me stranded for a long afternoon. First, don't just stand in the massive customer service line. The best way to rebook is through the app or a kiosk—it’s much faster. Since I had five hours, I headed to the SkyClub (you can buy a day pass if you have the right card). If that’s not an option, find a quiet gate with chargers. It’s the perfect time to modify your itinerary or just catch up on some Netflix!
