American Airlines AAdvantage - Called to exchange ticket home which was in Florida. Paid extra so I would have an exchangeable ticket so when I called to do this I was told that didn't matter if I had an exchangeable ticket, so I had to purchase new ticket for $350 to fly one way home after already paying $240 was a round trip ticket. Has this happened to anyone else? Also charged an extra $25 because I called them instead of doing it myself on my phone? Isn't that a ticket agents job to book flights? So confused & aggravated. I've googled this place and can't find any information as to Why? Why buy exchangeable tickets when it doesn't do any good? Any help on how to contact them would be great, probably will get a $25 charge if I call them!?!
