The 1-800 number is ok if you are a U.S. Citizen with a U.S. Phone, not good for us international visitors who would need a mortgage to phone it & wait in the que for an agent to become free to deal with you.
Last year our flight got cancelled at PHL, a customer service agent sorted us out with next day flights & hotel, but I asked if I could ring the guys meeting us to stop them going to STL to meet us as it's an hour & a half travel from their home to airport, I was told I couldn't use the phone, so had to use my UK phone! Cost more than I would have liked!
Prepared this year, I got a us PAYG phone just in case.
