My one-way was just for me.....could be because I booked it yesterday to fly tomorrow?
I don't think so. I have definitely booked 1 day in advance before. Did you call or book it online? When I look online, the flights tomorrow are $84.70 one way (I think the website charges a small fee vs. calling).
I would call and check with them or check at the airport. Seems too high!
