The boarding was great. With all the delays I was grateful to get on the plane and headed for home. There was no in flight entertainment. Seats were very uncomfortable! Unfortunately we were seated next to an exit row so there was no recline in our seat. Other than that it was a smooth ride.

The boarding was great. With all the delays I was grateful to get on the plane and headed for home. There was no in flight entertainment. Seats were very uncomfortable! Unfortunately we were seated next to an exit row so there was no recline in our seat. Other than that it was a smooth ride.

My flight was cancelled twice and the third time I tried to rebook it online I cancelled the flight because it looked like I would get a refund to my credit card. Instead I now have a credit. I was also on hold for three hours waiting for a representative and then disconnected. I will never fly delta again.

Flight for canceled. Horrible experience.. had to rent a car to drive myself up here.

Flights were terribly delayed. I was at At,anta Airport for over 4 hours waiting for my connection.

My flight consistently said it was on time and the plane didn’t arrive until after 30 minutes after take off and nothing was announced to passengers

The flight was canceled two hours before departure, it took over five hours to rebook us on another flight.

First, the flight was schedule to leave at 12:08. Delayed to 12:38. It is 12:58 and I am sitting at the gate. The staff are not communicating with us (just tell me it’s gonna be five hours if that’s the case, quit hufflepuffing around like you’re trying to board us when the plane isn’t even here and you don’t know where your crew are. I’m still waiting for any communication about the further delay. This is a rebooked flight from a cancelled flight yesterday, when the airline failed to fulfill its fiduciary responsibility to hotel and cover transport for overnight cancelations. Asking about the food on the flight? What food?!? Delta doesn’t serve meals unless you pay for them and you really want me to give delta a high rating for passing out processed snacks (fun size!)? Can we be for real. Delta is cementing itself in history as one of the cheap, stingy, outdated, glory days are over airlines, and it shows. I took this flight knowing delta was going to provide below level service but this is beyond burgers!! I can’t believe a multi billion or dollar company looked straight in my eyes yesterday and I told me this wasn’t their fault and there for the extra cost in hotel and hundreds of dollars in Ubers are MY RESPONSIBILITY. The only thing I am at fault for is believing delta is reputable company worthy of my dollars. I’m not even sure I want to be compensated unless it is cash because I would rather die never traveling again than to put money in their pockets.

The flight was great. The crew were a little terse about the size of my bag. It fit fine.

I know it was not in Deltas fault. But numerous delays and cancelations. I requested a hotel voucher and was told they weren't available. The lady on my hotel shuttle did receive one from American. Why the difference?

Flight was delayed. Had to get rebooked. Diamond medallion but stuck in a crappy seat. Rebooked flight then got delayed again. Then when we finally boarded, we waited another hour for a new crew. Then landed in JFK and sat for another 40 minutes waiting for a crew to come to the gate to be able to deplane. Hot mess all around, which unfortunately is becoming the norm for Delta

At least the delays were short. Business class, even in the new planes is very crowded now with crappy tray tables

There were issues with the first segment but what really bothered me overall is that you rebooked me and put me in a seat away from my wife and then put her in another booking or boarding group. I don't like having to monitor every little thing you guys do in order to get what I paid for in the first place.

See my previous comments. I was probably booked in business but was moved to economy

Delays!!! Serious delays. I was told by a member of staff in LGA that I would miss my DEN to LAX flight connection, so I was put on a later flight. Due to delays I would have been able to have made my original flight, where I was sat in business class - seat 1A: I was put on my original flight but bumped from business - 1A to economy 33C. I want a refund for paying business class but only flying economy

This flight was 2.5 hours delayed due to crew issues. This meant that we arrived after 2 AM. Very very inconvenient and we were not really kept well informed.

The new Airbus A231neo has neat tech but the economy seats are so tight together that I always had my shoulders against one passenger or the other. I was very miffed that Basic Economy REQUIRES check-in of bags other than your personal carry-on; if you want to offer low-cost airline prices and then add services for a fee, just let me carry on my duffel. Hell, I could have put my carry on IN the duffel and called it a day but the gate agent would not let me; I ended up paying $40 for the risk of losing my bag. Not the worst flight, but far from the best.

No water on the toilets, dirty sits. 4 hours delayed departure.

Boarding was efficient. Crew was not pleasant and skipped me during a round of beverage service. Older plane with no seat back screens and I couldn’t connect to wifi or their entertainment offerings.

My flight was delayed for a whole day, so I lost a day of my vacation.

I was refused to used the toilet closes to my seat and had to go to the back of the plane .. it was difficult for me I’m a wheelchair customer

Our 9:10 am scheduled flight continued to get delayed all day with no information given from the agents as to why. It wasn’t until I went to the customer service desk and got us switched to another flight at 2:44 pm (that wasn’t nonstop like our booked flight) that the agent finally was able to find out it was due to a fuel leak. I don’t know if our original flight ever took off but I don’t find it acceptable to leave people sitting in an airport all day with no explanation.

If there was enough room for me to bring my carry on luggage with me on the flight.

My flights had excessive delays, alleged mechanical problems, and overall terrible customer service

American dropped the ball on this flight. It was canceled after waiting on the tarmac for 6 hours. American airline was so greedy that they open the door after close, delayed our flight then caused the pilot to over 14 hours limit if they were to fly to Phoenix. So more delays and finally flight canceled. Horrible experience with American Airline in Philadelphia.

This flight was awful all around. Delays on the tarmac at PHL before takeoff and at the tarmac in Chicago caused me to miss my final connection. This was completely avoidable, in my opinion.

There were delays on both ends. It made it less than excellent. This plane was great though

Attendants were rude. Scowling. Seats were miserable and we paid extra.

Not being able to purchase my check in baggage online was a negative.

LATE LATE LATE!!! Plagued by late AA flights on this trip. Such a drag. This one was by far the worst.

Same basket of unhealthy prepackaged snacks (junk food) which was depleted by the time it got to my row!!

For the price we paid, the service was outstanding, we took off on time, everything went very smoothly, we landed on time, and we didn't need anything extra.

On a day with 1000s of worldwide flight cancellations, I was worried about my flight. Not only did my Spirit flight leave as scheduled, but it arrived at destination earlier than expected! This made my day!

The length of delays were extremely frustrating. Stuck in airport for hours. We were to get meal vouchers but it was 3 hours until someone responded to me from their WhatsApp and they said wait for an email. Still no vouchers and it’s been 24 hours. Terrible customer service. The ppl at the gates and bag checkin were miserable and not helpful

Spirit airlines is very bad airline staff doesnt know how to treat passangers they didnt allow us in the flight we reached 45 minutes ago from flight departure but they denied nd said you are late Very disappointed i never reccomend spirit airlines

spirt air lines took advantage of two eighty year olds. we paid extra for cancelation due to health reasons they did not honer they have no spirit. I hope they treat there grand parents beter.

Our flight was delayed four hours and staff did nothing to accommodate the issue.

The flight has been cancelled we have been waiting at the gate for almost 2 hours and they didn't gave me an update for rebooking

Would have been better if I would’ve made it on my flight but it was delayed twice and then canceled and now I’m stuck till Monday which was and extra 5 days I did not count on .

Awful. My flight was three hours late leaving DFW and we just arrived at LAX three hours late and stuck on the runway. I heard the Spirit workers at the desk in DFW say that we were waiting on a crew. I am extremely disappointed in Spirit.

Delays and sending me to different terminal for departures. It looked very confusing and disorganized

Better than expected.on time. Friendly staff in NY however MYR not so nice.

The flight crew and flight attendants are poorly trained and demonstrate poor professionalism. They have a sloppy appearance and communicate with patrons poorly. It is embarrassing for them to be representatives of an airline and for them to be called professionals.

After 5 hours of delay, they cancelled the flight. Very disappointed

My flight to LA was cancelled. I waited at the airport for 3 hrs saying it was delayed and then all of a sudden it was cancelled. Frontier only gave me a voucher and refund but could not rebook me. Flights on other airlines were too expensive last minute. I had to drive down to LA and didn’t even take my return flight home since I had to drive. One of the worst airline experiences in my life. It’s crazy how airlines can just upend people’s plans just like that.

Flying Frontiier was extremely poor!! I paid for a7:15am flight on flight 1601 from PHL To Las Vegas and the delay was brutally, excruciatingly and disgustingly long (8 hrs). I arrived by Uber to PHL at 5:30 am and had to spend the entire 8 hr delay inside the airport. Even more atrocious was that the flight was delayed twice. On the phone with customer service for two hours and was not fully compensated. I feel taken advantage of with this airline. They offered a menial couched for another flight within 90 days to me and my husband who has never flown but this experience has made us almost 100% sure to not fly this airline and will suggest that others don’t either. We don’t want to book ever again, don’t want a menial voucher and I believe by standard and because the flight was delayed for 8 hours, I should be fully reimbursed for the entire round trip. There is no excuse why this should have ever occurred. After sharing my experience with others in Vegas and Philadelphia, I was told that Frontier airlines is notorious for long delayed flights, poor customer service and refusal to compensate people correctly. I’m very nervous to see what departing from Vegas to Philadelphia will bring.

I fly Frontier often and generally don't have any issues. For some reason, the Denver to Houston's George Bush Intercontinental (IAH) flight always needs to wait on the tarmac in Houston because a gate is not available after landing. I've been stuck for as little as 15 minutes and as much as a little over an hour. I know only fly the Frontier Denver to IAH route when there is not an available flight to Houston Hobby (HOU).

Flight was 3 hours late leaving. Poor communication from the staff about delays. Impossible to get in touch with customer service (by design). And it actually didn't come out to be much cheaper than a non-budget airline! Not worth the headache, I'm never flying Frontier again

I’ve never flown frontier without a flight getting canceled. I understand that things go wrong with planes, but all other airlines handle cancellations so well. Frontier becomes a dumpster fire if a problem appears for them.

Checking in was easy and simple, crew was nice and efficient, but I would improve seat assignment randomness to make it easier to sit together based on when you check in. Overall would fly with them again.

Flying Frontier was a nightmare. From the booking through Kayak, checking in, departing and arriving, I will never recommend Kayak or Frontier.
