Our flight was delayed almost 2 hours. Crew was pleasant, but the seats were so uncomfortable for a 3 hour flight. Would rather spend the extra money for a ticket on a nicer airline. They just keep getting worse!

Its a cheap flight... that's why we all book Frontier...

There is no excuse for waiting 45 minutes on the runway before parking the plane. It's claustrophobic, the plane was so incredibly hot temperature wise, making everything very uncomfortable. It was extremely frustrating. Your flight attendants have always been good though.

Nothing

Flight delayed from 8:00 to 12:15 AM. Checked in at 6:00 PM, left airport to eat, returned back 2 hours prior to departure and TSA was closed and would not let us back to the gate. Frontier was no help. Missed the flight, had to drive 2 hours from Cincinnati to Columbus to get another flight at 6:00 AM

On time

Your staff s not trained to make common sense moves to be flexible when external forces call for action such as the I 275 closiure overnight which led to extremely long lines at check-in Thursday AM. Instead of calling for the 5:30 flight to come up first, we hard to stay on line until I asked other passengers to let us ahead. Then 4 of us where unable to be processed in time- it would have taken another 5-7 minutes which could have been made up in air. Then the 1 passenger who absolutely needed to be in Seattle that afternoon for a once in a lifetime tryout with the Mariners, your staff refused to talk to- instead telling him to step aside with us until the next plane had been boarded and then the next. I finally made arrangements for him to fly Southwest myself. Another passenger missed a wedding rehearsal dinner. Your inability to be flexible cost us all extra money - me in twice the Uber fees to get back and forth to the airport- and valuable time which is a commodity you can never replace. Your cheaper option is one I will tell everyone to avoid like the plague.

It got us there and back for a descent price. The flight was fine but the seats are not comfortable and do not recline. I wouldn't suggest Allegiant for anything more than 2 hours and that was even pushing it.

We arrived 3.5 hours early and the line was very long. They must have had a system glitch but didn't communicate to anyone in the line as to what was going on. When it did come time to board, they told everyone in the line that was going to Cincinnati that we couldn't check in until 2 hours before the departure time. Apparently there were some other flights that left before us. If they had told us to keep our place in line and to let other people through, that wouldn't have been a problem. But, they didn't. Their own website says you should check baggage at least 2 hours before your flight and no more than 4 hours before. They took it upon themselves to change the rules on people who arrive early. Then, once they no longer had anyone else to check in, they changed their rules again and start checking in people for Cincinnati about 2.5 hours ahead of time. A little communication and brain power from the staff would have gone a long way. After all that mess, the flight was delayed leaving about 15 minutes without any updates from Allegiant either.

It got us there and back for a descent price. The flight was fine but the seats are not comfortable and do not recline. I wouldn't suggest Allegiant for anything more than 2 hours and that was even pushing it.

We arrived 3.5 hours early and the line was very long. They must have had a system glitch but didn't communicate to anyone in the line as to what was going on. When it did come time to board, they told everyone in the line that was going to Cincinnati that we couldn't check in until 2 hours before the departure time.

Then, once they no longer had anyone else to check in, they changed their rules again and start checking in people for Cincinnati about 2.5 hours ahead of time. A little communication and brain power from the staff would have gone a long way. After all that mess, the flight was delayed leaving about 15 minutes without any updates from Allegiant either.

It got us there and back for a descent price. The flight was fine but the seats are not comfortable and do not recline. I wouldn't suggest Allegiant for anything more than 2 hours and that was even pushing it.

We arrived 3.5 hours early and the line was very long. They must have had a system glitch but didn't communicate to anyone in the line as to what was going on. When it did come time to board, they told everyone in the line that was going to Cincinnati that we couldn't check in until 2 hours before the departure time. Apparently there were some other flights that left before us. If they had told us to keep our place in line and to let other people through, that wouldn't have been a problem. But, they didn't. Their own website says you should check baggage at least 2 hours before your flight and no more than 4 hours before. They took it upon themselves to change the rules on people who arrive early. Then, once they no longer had anyone else to check in, they changed their rules again and start checking in people for Cincinnati about 2.5 hours ahead of time. A little communication and brain power from the staff would have gone a long way. After all that mess, the flight was delayed leaving about 15 minutes without any updates from Allegiant either.

I arrived to the airline desk 43min before takeoff and they would check my luggage. I was 2min late! They didn't even try, manager just said, they're really strict. Then, had to pay $99 extra to board the evening flight. Also, they don't make you aware that you have to pay for a carry-on. Terrible airline!

Nothing

Flight delayed from 8:00 to 12:15 AM. Checked in at 6:00 PM, left airport to eat, returned back 2 hours prior to departure and TSA was closed and would not let us back to the gate. Frontier was no help. Missed the flight, had to drive 2 hours from Cincinnati to Columbus to get another flight at 6:00 AM

The price of the trip does not include a carry one. This is difficult when all other airlines are not charging for a carryon. This increased the cost of my trip dramatically.

Its a cheap flight... that's why we all book Frontier...

There is no excuse for waiting 45 minutes on the runway before parking the plane. It's claustrophobic, the plane was so incredibly hot temperature wise, making everything very uncomfortable. It was extremely frustrating. Your flight attendants have always been good though.

On time

Your staff s not trained to make common sense moves to be flexible when external forces call for action such as the I 275 closiure overnight which led to extremely long lines at check-in Thursday AM. Instead of calling for the 5:30 flight to come up first, we hard to stay on line until I asked other passengers to let us ahead. Then 4 of us where unable to be processed in time- it would have taken another 5-7 minutes which could have been made up in air. Then the 1 passenger who absolutely needed to be in Seattle that afternoon for a once in a lifetime tryout with the Mariners, your staff refused to talk to- instead telling him to step aside with us until the next plane had been boarded and then the next. I finally made arrangements for him to fly Southwest myself. Another passenger missed a wedding rehearsal dinner. Your inability to be flexible cost us all extra money - me in twice the Uber fees to get back and forth to the airport- and valuable time which is a commodity you can never replace. Your cheaper option is one I will tell everyone to avoid like the plague.

Quick, cheap and efficient. Flight was on time departure and arrived early. Check in was quick and efficient.

I hate the nickel and diming that Frontier does. I wish that water was at least free.

they couldve sent me an email suggesting I check-in and get my boarding pass electronically. I thought my confirmation and my seat selection was sufficient. when I arrived 40 minutes before my flight I was told sorry, comeback tomorrow, and its an extra $99.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
