Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

2.0 MediocreErick, Oct 2024IAH - LRD

Everything was awful Flight attendant was condescending, rude and not helpful at all. Small outdated plane. No service, uncomfortable seats. Flight attendant was really the worst. He used hand gestures to communicate instead of words and whenever he used words he was condescending.

Poor and identical to the first two legs, except for the crew who were patient, professional and of pleasant and jovial disposition!

The entertainment would not work. The comfort of the seats leaves something to be desired, pretty uncomfortable.

My flight was completely full. Making me very stressful with people walking around all the time. I believe airlines can do better for entertain people during the flight.

Everything was very good. Was able to change a make run flight leaving on direct earlier in the app -seamless!!! Well done

Being stick waiting for gate at ORD cause me to almost miss my connecting flight…being deaf United made no no effort to keep me updated as I couldn’t hear the PA

Delayed over an hour due to paperwork not being filed correctly. Forced to change planes.

The departure was delayed by 1 hour. The seat was comfortable and selection of entertainment is very good.

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

Clean and plenty of room for handbaggage. Leg room was cramped compared with the 777 from Frankfurt.

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

3hour delay In the last 3 months i had 3 flights and 2 of these had a more than 2:40 hrs delayed

My initial flight to ORD was extended without reason. We circled the airport a few time and then drove on the ground for at least 20 minutes. These kinds of delays are annoying but somewhat expected… it would be nice if the crew would make an announcement to give updates on how long we could expect to be delayed.

The flight was uneventful. What was a problem was I was delayed getting home one entire day because the flight from Sacramento was delayed. That made getting to my connecting flight impossible. I had to stay another night at the hotel and incur that expense as a result.

This flight was fine but had no time to breathe as the connection was late from Sea to ORD.. Super stressful. If we checked bags, the trip would have been very distressed.

Seats were very uncomfortable. I paid extra for a seat with more leg room, the seat was no different than a seat at the back of the plane. Flight attendant was rude.

the food choice of packaged chips and popcorn was utterly ridiculous for first class

Check in agent was helpful and nice. Flight was OK. Our flight in Chicago was delayed 8 hours without an explination. This was our journey home. After a horrible flight experience on on the way to our vacation where our plane was diverted for an emergency medical issue, was grounded for hours, we missed our connecting flight by 25 minutes, and it took a day yo get re-booked, this was yet another bad experience that American seemed unwilling to help out with, much less compensate us for the

Late and next flight even later. Who leaves at 245 am and arrives at 330 am ? No wifi, 4 hr flight and one bag of pretzels? AA should be ashamed

No problems on this flight. Entertainment system worked well. On time take off and arrival. Smooth most of the way.

The flight landed with a delay and we had to wait almost an hour to be off boarded. So typical of spirit.

The gate employees and the flight crew were friendly and professional. Afterboarding we waited 20 minutes for another flight; a complimentary beverage would have ben appreciated for the inconvenience.

Everyone on the plane was wonderful. I can't say that the trip of flying was wonderful because I hadn't done that since I was 13 years old. Honestly I was terrified. What would make it better is if they didn't drive so fast but I know they have to. And if they could go up slowly and land slowly. But none of that they can control.

Horrible experience, they cancelled the flight , and we had to lose money on car rentals and hotels and tickets for extraction

You get what you pay for, but those tickets weren't cheap, so I expected better, but Spirit is just one of those airlines.

Terrible airline. Cancelled the flight less than 24 hours before the flight. Caused me extra expenses!!! This will be the last time me and my family will travel with them

Very long delay of 6hrs with poor communication from airline. Another 5 pm flight to Miami left on time even though ours was scheduled to leave before that at 3. Would only fly Spirit when you have flexibility for cancellations or delays

Horrible They let some flights go while others where grounded or cancelled. Understanding the storm but there is always a way to get it done when you actually care about the people that are not from the place they are leaving from.

Terrible airline, NO REFUNDS!! Only credit for another spirit flight

Cancelled the return flight moments before boarding, horrible customer service in assisting with any rebooking. Never again will I fly Spirit.

Stop changing gates at sfo. When you are elderly going back for it’s not fun.

We understand and comply with Frontier’s bag sizes. We’ve had some problems in past while having to await other passengers who do not understand the baggage restrictions or have not prepaid and that is usually our biggest concern (others delaying us) with flying Frontier. Flying OUT of ONT, however, has always been a great experience. I’ve also noted even on delayed Frontier flights very knowledgeable pilots who manage expectations well.

There was no easy way to check in. I don't want to install an app to checkin. I will use alaska from now on because they have a web check in method that is easy.

The crew was ghetto lol I felt like I was on an inner city field trip

Horrible! The short distance flight ended up taking 5 hrs! There was a 3 hr delay for the flight to take off and there was a 70 min wait on the tarmac for some bogus reason that the pilot said the gate he was supposed to board was taken up. After a 30 min wait he said the plane that was supposed to push out of the gate called a medical emergency and 40 min later he ended up boarding another gate. For the initial 3 hr delay there was no information/alert about the gate or delay in the app or the boards up until the boarding time and even beyond! Had to walk all the way to the end of the terminal to find the frontier staff to ask what was going on. Avoid this airline at all costs! If you have carryon bags or checked bags , their prices come equivalent to the prices of more reliable airlines. They are the worst in timeliness at 60% (reported as delayed) this year (check the data) by a high margin even compared to the second worst airline. If you are ok with having a miserable flight experience with the odds close to flip of a coin, feel free to try them. If you value your time , money and flying experience, stay away.

There was nothing to like, flight delayed had to move to different departure areas, disorganized to say the leasr

Delayed for two hours due to trivial issues. No reimbursment. Also on arrival further delay due to terminal malfunction.

Our flight was canceled for no known reason. We weren’t told until we were checking in at 5:00 am. This was after our last flight with Frontier where we sat on the plane for three hours (not an exaggeration) before we took off because of a mechanical issue. We won’t be flying Frontier again.

Allowed me to chose my seat without extra charge (I purchased full-price ticket) and boarding was in group1. Didn't even serve water.

I went to the Frontier counter in San Jose at 1030am or so on Sunday 10/13/24 to see if I could get an earlier flight to San Diego in lieu of my reserved 630pm flight. One thing led to another, and I was able to obtain an open seat for about $ 56. on the earlier flight. Fine. Then the agent asked if I "was checking a bag". Not knowing that carry-ons cost extra per Frontier policy, I thought that she meant a regular checked bag. Therefore, I said no. Once I got to the gate, the same gate agent who sold me a ticket told me that I had to pay $99 for a carry-on, and that all bags were extra on Frontier. Having never flown on Frontier, I was not aware of this. Part of the issue was that she was not a native English speaker, so there was a miscommunication as to what "bag" meant. I would have preferred for her to have clearly let me know at the front counter that any bag including a carry-on cost $99. It would have had the same outcome, as I had to take my carry-on. But it got hectic at the last minute at the gate itself. The baggage policy should have mentioned "including carry-ons" when we first spoke.
