We were early for our flight but still got delayed because they didn't let us board
    I would never fly Frontier Airlines again. Last week we have a 7am flight departing Denver on Friday morning. We arrived at the airport at 5.30am to check in for our flight, we had to check bags so we figured we would just check in at the gate. We waited in line to check in for 45 minutes. But got on the flight 10 hours after.
    Full Fright
    We waited in line to check in for 45 minutes and when we got to the check in counter, the lady stated that their system had locked (it was now 41 minutes before our flight) and we were not allowed to check in or attempt to catch our flight. Their policy is that you must be checked in 45 minutes before departure or you are out of luck, we were 4 minutes late but had also been waiting in line for 45 minutes. The front desk lady was extremely rude and unhelpful and just continued saying "well do you want to pay the $50 per person to change your flight to 5pm tonight", we did not have any other option. The kicker was we took the 5pm flight and of course checked in 45 minutes before, it took us under 15 minutes to get from the check in counter to the gate, we could have caught our flight in the morning without any issues. Poor customer service, terrible policy, took no responsibility for the 45 minute check in line. Absolutely disgusted and will never travel with them again.
Frontier Failures
 They don't get anything right. 


 The worst airline I've flown. 


 Depending on which rules they choose to enforce, you can never be assured that you will be granted access to their boarding process. 


 I have never had a more infuriating, more frustrating, or more demoralizing experience traveling in my life! 


 This airline is awful. They nickel and dime you, they are rude and unorganized. I will never fly this airline again...EVER
