What can I say except meh. I forget why I had a ticket for US airlines, but it was probably because they were the cheapest or best time slot. It may have been both since it was for work and they give you very little flexibility on cost.
Anyway, I had a credit to use, and use it I did. The whole experience went strangely smooth. I got email reminders, checked in online, got to the airport on time, and the flights left more or less on time.
My biggest gripe is the outrageous cost for any seat that is not the middle. I pre selected my seats a month ago and no charges were visible. Needless to say, this was not the case when checking in the day before. The one small mercy of a connection is not being stuck in the middle for an extended period, I had to get up to leave the plane.
