I booked with Travelocity in June, 2011, got my conf. e-mail, departure date was correct, didn't pay attention to return date, (my mistake).
On the day I was to leave I noticed my return date was 8 months later. I called and Travelocity would only change the ticket if I paid $180.00, plus $30.00, plus additional $600.00 extra price on the ticket.
I will never ever use Travelocity again, they are thugs. I had a terrible time trying to understand the representative when I called, but I got that they were going to charge me more money, for what I believe to be their mistake.
