Poor customer service, no accommodation for passengers when the flight was delayed over 5 hours.

The flight was late. The crew was rude. There was no food. Cramped and uncomfortable. Nothing about this flight was good.

It was great. The gate staff were very helpful in Portland when my son forgot his rolling bag and had to go back to get it just in time to make it on the plane. We really appreciate that. Great job!

This leg was much better, but we did have to have a 3 hour lay o er after coming from a very exhausting hiccup with our flight from BNA to Den

My flight from Denver to Minneapolis was excellent. My flight from Minneapolis to Denver was one of the worst I flights I have ever experienced. I had a window seat, the gentleman in the middle seat was morbidly obese and SW should have made him purchase two seats. His elbow dug into my arm most of the way even after I asked to please be careful. I was literally squashed between the him and the window with no wiggle room. The plane was full so it was not possible to ask for a different seat. I realize I should have complained to the flight attendant but I didn't feel anything could be done to rectify the situation. I fly SW often, I will continue to do so as this was my first negative experience.

Everything went smoothly and we even arrived a little bit early.

Connecting flight is on time and boarding was a breeze!

WiFi did not work. For as outrageous as these flights cost, when they’re advertised with certain services/ features they should be in working order

I would have liked to arrive on time - not 5 hours late!

1.5 hour delay, poor service, no compassion from the crew. Terrible experience

Flight was late to take off Plane broke down Had to move everyone to another plane Told we weren’t going to LGA but Newark Also told we would be taken to NY But United lied and we ended up at Newark at 2 in the morning Horrible experience. And the experience of trying to get compensation from United is just as bad. They could not care less about their passengers Never again!

Flight was delayed “due to earlier delays of that plane”, so we were nearly three hours late.

Very easy ! Use the kiosk and bag drop and right to security within 10 min

This planes staff was top tier. Everything went great and had a great flight home.

Destroyed my suitcase. Tired of talking about it. Cancelling my unite mileage plus account.

New plane was lovely. Crew customer service is always lax but expected. Kraft on time and arrived safely.

It was a short flight so I was expecting too much

Had a one hour delay due to mechanical issue. I didn’t think I’d be able to make my connecting flight, but they waited for me and greeted me when I arrived to help things run smooth.

O’hsre taxi and deboarding took 40 minutes. Needed 20 minutes extra time between connecting flights to avoid running through terminal.

Ok so apparently the new policy on United Airlines is that customers in the main cabin should NEVER be served more than once and besides picking up trash there should NEVER be another interaction with the customer for any reason.

It was poor a four hour delay and no explanation for the delay. What’s a 35 dollars going to do. It also made me miss my car rental,

It was on time. Flight was comfortable. Staff was nice. It was the way a flight should always be.

The price was the only good thing about this flight. It was scary during takeoff when the plane tilted side to side. It made me feel very nervous as I have never had a take-off that unsmooth. There was no on-flight movie or music options and the only complimentary option was water. Other airlines offer trail mix or a caramel cookie and pop options as complimentary. This flight was a 2.5 hour flight. I understand for shorter flights not having options, but a flight 2 hours or longer should offer more complimentary options and in flight entertainment. Also the seats did not recline and for a longer flight reclining seats are a must for comfort.

A very pleasant flight but it would be greatly improved with wifi to help entertain kids

This is a no frills, get it done, efficient airline. The seat is a lawn chair. You better bring your own entertainment. If you want something other than water you need to pay for it. But they will get you to your destination quickly, on time, and then they will turn the flight around and go right back where they came from. Reliably. Couple times a week tops. If it fits into your schedule, you can’t get there cheaper or faster.

A three hour delay to board and then another hour on the tarmac because they couldn't get a tractor? Ugh.

Allegiant canceled the flight. The flight the next day was full. Allegiant did not provide any compensation besides a refund. Last time on Allegiant.

Seats were very uncomfortable and being charged for snacks and water.........

Allegiant actually impressed me, original inbound flight from PBG was so late they gave us a bird inbound from Des Moines and only left 1h late and gained 40 minutes back in the air. Comfortable flight with no frills but no complaints.

Clean, friendly, roomy. But check-in from the phone link was terrible. Repeated attempts wouldn’t save at the final step. Just kept spinning! It was very frustrating. Finally, I used the app (vs website link) to check-in which worked very smoothly on the first attempt.

The flight attendants were extremely sourly and borderline rude. I did not feel appreciated as an AA customer once.

As we approached Denver, we encountered quite a bit of turbulence. I know this can sometimes be the case as I frequently fly this route but not on American. My gripe: Usually a pilot or co-pilot alerts passengers to the possibility of turbulance ahead of time. This did not occur nor did he communiucate during what was a pretty rough ride.

Terrible. Our luggage was delayed and couldn’t be delivered for several days. We got bad information from the airline agents at baggage claim. We had to pick up our car so we wouldn’t be charged for an extra day. We got lost in the maze of airport parking. The baggage claim agents didn’t offer us any compensation for our extra time and expense. We are tired, hungry and very frustrated.

Mechanical delay and no compensation. Missed connection as a result of their delay. Mediocre performance and service. Horrible airline currently with horrible culture.

Any sort of gluten free snack option would be nice

Crew was late. Baggage was late. 2hs inside the plane waiting fro de-icing and traffic. A 3:30hs flight ended up being almost 6hs inside the airplane.

Timely boarding process, made up for lost time even after a lengthy wait for de-icing

It would have been better if I could have had my flight on time. It was delayed for 5 hours. Caused me to not be able to fulfill my promise to my granddaughters. Other than that it was a good trip.

11h50m total delay. Had to switch to another flight that was still a 7h30m delay.

I was assigned an aisle seat but when I boarded the plane a person was already sitting in my assigned seat. The flight attendant was ready to help me get my original assigned seat, but I chose to simply take that person's assigned seat in the next row back in the middle seat. I didn't want to make a fuss, just wanted to ensure that I didn't accidentally create a domino effect of accidentally taking another person's assigned seat, etc. While the middle seat is not the most comfortable, it was a quick easy flight and I'm grateful that the flight attendant was ready to help me out.

I paid for the upgraded bundle. Was worth it! Great experience round trip!

It was awful everything about it terrible I will never ever ever ride it again

Crew was kind of grumpy and there was no beverage service at all. Sodas were $4. Disappointing.

12 hour delay required getting on and off plane 3 times - would have at least liked to have been offered a snack or drink

There's no seats that lean back with little leg space i wad uncomfortable the entire flight. Your charges for extra baggage is despicable and costly!!

There was no food and no entertainment, so I'm not sure why these are even in the survey, as my understanding is frontier does not ever offer food without a few, not even a snack, and there are no screens so unless the flight safety talk is our entertainment why ask how we liked it?. One of the flight attendants say in the back of the plane as people filed in to their seats, yelling orders about where to put baggage and telling people to hurry up. It was the least professional experience I've ever had on a flight.

Not clean and was told I would get a great seat and it was not great at all

Delayed. Text notifications were slow. Not much information o what was happening. Boarding was slow and confusing. Wasn’t even offered water other flight. Had to ask. No entertainment at all. Felt like.a Greyhound bus.

Frontier is the Walmart of airlines. Frontier has removed adjustability and comfort from their seats to make the flight lighter and save gas. This makes it impossible to sleep on their flights. Their customer service is abysmal. Once, I bought a drink on the plane, and they swiped my credit card on the plane to pay for it. Then I got three weeks of daily notices from my bank telling me they tried to charge the wrong card number over and over again. I tried to call them, but they removed the ability to actually talk to someone that can resolve such a problem from their company to cut corners. The only way to talk to someone in person is to go to the check-in counter at the airport (40 minutes drive from my house). Eventually their system gave up on trying to charge the card, after 21 days of repeated tries. They don't pad their prices even a little to handle customer service issues like missed flights. They also have a blanket policy preventing helping you reschedule a missed flight if their system says you "cancelled" your own flight online. This is a major problem because their website is broken on mobile devices, the only web browser you have at the airport when their gate staff tell you that you have to reschedule your own missed flight online because they can't help you. I tried to reschedule my flight on my android device and instead, their website crashed and "cancelled" my missed flight. When I got to the counter, the agent argued with me for 5 minutes insisting that I intentionally cancelled my own flight (implying I had to buy another flight). She missed the point: the problem was that I could not buy another flight because their website is broken. I left to avoid more conflict with the "customer service" agent. I tried to redress my issue with their only other "customer service" chanel available: the contact form on their website. The response I got was more of the same: you cancelled your own flight, according to our website / computer records, therefore we won't help you. I was trying to explain the problem with their broken website that cost me hundreds of dollars by crashing / malfunctioning and resulting in a cancelled flight, but they only had deaf ears for this problem. Worst customer service I have ever experienced. I will never buy another Frontier flight again, because it is a risky, painful move that I will likely regret often.

My experience with frontier staff at the Denver airport was absolutely horrible. The manager on duty was even worst if was the worst experience I have ever had, I have never been treated so poorly as a customer in my life! The staff was extremely rude, eye rolls and attitude and then refusal to help me at all. I wish I could never fly frontier again that’s how horrible it was!
