Just got off the phone with an American Airlines agent after going online to switch to an earlier flight and being quoted $1,100. When using the aa.com, the person who made the reservations did not realize they had mixed up the departure and return times. After catching the mistake, I've now been quoted over $800 to fix it! The entire reservation was only $880!
I've never had these types of issues with Southwest...maybe since I've flown so much with them. Decided to give AA a shot and realize now the folly of my ways...guess this is why they have a site like this...
Honestly, always expect some charge and was prepared to pay the $300 and even a bit more...but doubling the cost...is just bad customer service. Not sure what other business could get away with something like that without going out of business.
