Frontier is horrible!
    Frontier Airlines caused us to miss our connecting flight and refused to do anything about it. They didn't even offer us an apology.
    Full Fright
    Arranged a round-trip flight from Chicago to Punta Cana, Dominican Republic. We arrived back to Chicago at 6:00 and had a connecting flight to make at 9:00 through Spirit. We were unable to deboard the plane until 7:20 due to an unspecified problem at the gate. They moved the plane to a different gate and we ran through the first customs to get our checked bags. Somehow there was an  issue with Frontier's luggage crew and they couldn't get anyone's luggage to the carousel. We waited at the carousel until 8:45 when our bags finally arrived. We sprinted through the airport but we're unable to make our connecting flight. We had to pay $100 through Spirit to reschedule a flight 24 hours from then. We went to the Frontier desk and asked for at least a hotel voucher since we were stuck overnight and they refused. They took no responsibility and said because we landed on time (even though we could not get off the plane for an hour and 20 minutes) we were out of luck. When we pointed out the entire plane did not receive their luggage until 8:45 they again said it was not their fault and they would do nothing. So now we're stuck In Chicago for 24 hours in nothing but beach clothes at below zero degree temperatures and not even so much as an apology. Screw Frontier Airlines.
Frontier Failures
 They don't get anything right. 


 But Frontier has LIED, telling AMEX we flew all four segments which is an absolute lie! 


 ...we were short a stewardess for our flight and we had to wait for them to arrive from another city...Completely unacceptable. 


 This airline is an absolute joke, they nickel and dime you for everything, there is no customer service, and apparently the idea of a flight going as planned is impossible. With the arrival of United and Delta to our area never again will I fly with Frontier 


 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
