At Trenton airport, Frontier still sucks!
    I do NOT recommend this airport, Yes the Frontier flights are super cheap, but DO expect to get what you pay for.
    Full Fright
    Yesterday my nieces and I were flying out of Trenton to Milwaukee, my nieces are 16 and 13 and had their own reservation so technically they were "alone." We arrived just a few mins before the cutoff time of 45 (you must check in or you cannot board the plane) we had a bag to check in so we chose not to do the online check in, since I knew we would be stuck in line anyway. The kiosk told me I had to get in line to check in, before I knew it I overheard other passengers saying the plane left early (by that time we had been in line for 15 mins). Other passengers also going to Milwaukee had online boarding passes in hand, it didn't matter nobody was getting on. I stood in line for 30 mins to be handed a business card with a phone number to call to reschedule our flights. This staff is rude and really could care less that people are stranded. People were panicking, freaking out, crying, all of the above, Frontier did not care. Later I found out the flight actually left 30 mins late, not early, either way they would not have let people on past their 45 min check in rule. I was on the phone for 2 1/2 hours with this crap airline, they are very policy oriented and refuse to bend any rules to accommodate their customers. I was forced to pay $75 for each child to reschedule their flight and lost my entire fare because my value was lower than the fee. I lost $350 total. Bottom line, if you choose to fly out of Trenton expect to receive crap service, crowds in a small space, rudeness and an overall dirty atmosphere! Oh and if you decide to give Frontier your business be prepared to follow their rules to a "T" or expect to pay some hefty fees. Lesson learned, PHL might be larger and more chaotic but I feel it is better to pay more for a flight and get great service than to pay for a cheap flight and be treated like crap and have to hang out in a dirty, old airport with no amenities. Do not fly Frontier!
Frontier Failures
 The sexism and harassment was visceral and cruel by male agents. 


 They don't get anything right. 


 Air crew forced us to violate FAA’s on-board regulations! 


 Cheaper isn't always better. 


 Traveling Frontier has been one of the worst experiences I have ever had. Rude, disrespectful and completely unhelpful. I would highly discourage traveling with them
