Flight attendant was amazing!

My flight however from west palm beach to Trenton on Sunday was NOT as pleasant... arrived and they told me I had no seat! Really!!?? I had to wait until everyone had boarded! Talk about stressful! Return flight last night was awesome

Feb 12, 2020

The website would not allow me to put in my trusted traveler number (grayed out) but the checkin agent took care of it so we got tsa precheck on our pass and went through that at security.

Dec 14, 2019

Online check-in on server took longer. This is a good choice if no bags.

The airlines charge for everything these days which seems like it would be better to buy a more expensive ticket versus the headache of being nickel and dimed for individual things. Frontier was fine. The airport however, including some of the TSA agents sucked bad! I will avoid Trenton at all costs.
