Sigh...
The JetBlue fare expired, but I still was thinking of flying out a day earlier than scheduled (one way flight is $69 for 10/30... I paid $45 for the 31st, so it would only be $69 more to fly out a day earlier....)
I tried calling Frontier to find out about this. That was a disaster. I'm not sure why but I was not able to communicate what I wanted to do, or the person I spoke with could not understand it. They wanted to cancel both parts of my trip, not just the first leg, and then said I should just change the first leg for the $99 fee...
So I tried tweeting @frontiercares as well, and they also were not much help.
So I'm just going to stand pat with my current flight.
It's really a shame for Frontier. They could have gotten an additional $69 out of me, but because they can't clearly communicate what their policy is, I'm standing pat to avoid either accidentally canceling my return trip or having to pay a $99 change fee on a $45 fare.
