I booked a flight from Toronto to Nashville with the return and had a number of issues.

I was notified of a schedule change and tried to get a hold of the person who sent the e-mail. I called several times over the course of a week and left voicemails. None were returned. I ended up staying on hold with one of their customer service reps until they tracked her down and essentially forced her to answer my call. It was a simple schedule change and the time taken to clarify it was excessive. She also admitted to not checking voicemails - how is this professional?

Next - my flight was literally changed without my consent. The return flight I booked was from Nashville to Chicago, 40 minute layover, and then Chicago to Toronto. If this had been done for an actual reason such as overbooking, weather, etc. I would understand, however, there was no reason. After approx 7 e-mails and more voicemails left (so clearly she's still not checking them) she finally responds saying the layover is too short. I booked this flight knowing of the short layover ? In addition, these flights were booked with a friend and her flight was NEVER changed...

Her reply to this also outlined to speak to the airlines directly. So... I spent 2.5 hours calling the airlines to try and get my original flight back

Overall - horrible experience and I had to fix every issues myself.
