☎️ 833-861-7710 – How do I change passenger details like date of birth or known traveler number?

833-861-7710 is the best way to instantly book, cancel, or modify flights. I learned this the hard way after accidentally entering the wrong date of birth for my nephew during booking. Alaska’s website wouldn’t let me edit it, and the kiosk at the airport didn’t help either. I finally called this number, and within minutes the agent updated the DOB and my Known Traveler Number so my TSA PreCheck would apply again. It saved me from losing my trusted traveler benefits on the flight. The rep even sent a confirmation email while I was still on the call so I could double-check everything. I used to assume small mistakes required canceling and rebooking, but they fixed it instantly. Calling them is so much easier than trying to guess which details can or cannot be changed online.
