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!

The crew was very nice and respectful and everything went well.

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

Nothing bad to say about the actual crew or airline. It was nice to have a complimentary FULL can of soda, as well as a snack. Blankets and earbuds were also provided at no cost for this red eye flight. I especially appreciated the free WiFi and movie selection with the Bluetooth option. It helped the flight pass more quickly. No matter who you fly, boarding and disembarking are always SUCH a pain. As I mentioned, this is on the passengers and not the crew!!

Flight attendants rude and impolite… flight delayed by almost 5 hours.

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.

the first flight smelled like urine Ac didn’t work pathetic experience

We were delayed due to a mechanical issue, but the gate staff and then later captain were giving thorough and frequent updates. Ended up being delayed about an hour, but we did get out, so it was overall a good flight!

My luggage never made it, I booked business class only to find out I’m sitting in the back. Very disappointed with the reservation

I found the seats ergonomically uncomfortable forcing the body to seat slightly hunched. For a short flight I worked on adjustments but for a longer flight, it would be difficult.

I cancelled this flight 2 days before departure but I followed your texts and emails and IF you were correct this flight turned into a nightmare.

The seats. The seat in front of me was awful and when the guy sat down, it flew back and hit my head when I was putting my backpack under the seat, It didn't make for a pleasant experience,

Cancelled flight. Still waiting to get home for grand daughter’s graduation .

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.

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

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.

Flight delayed 4 times on a non-stop from BOS to SFO. Then when landed in SFO had to wait for 30 mins for a gate AT 3:30AM.

Plane was delayed multiple times. I would like to request a refund. Was due to arrive Thursday evening ended up arriving Friday morning.

The seats were roomier than other airplanes I’ve been on.

The security line at JFK was one of the longest I’ve ever experienced - probably 45 minutes. I don’t know if JetBlue has control over it, but it detracted from the overall experience. Entertainment had good options, but the volume control was a bit small to tap on and the screen had a fair amount of interference blips. Clearer picture would have been better.

I liked the entertainment on JetBlue, the service from JFK to JAX was terrible at best

I usually dont fly JeTBlue and I dont think I will ever do it again. The flight was delayed fee time, nobody was giving us any info at at the airport, gate changing, the slowest and poorly organized boarding ever, rude staff.. huh

Purchased through 3rd party vendor which made everything difficult. Unable to check in online. Unable to get flight updates easily, tsa precheck information didn’t carry through, longer time to check in in person. Entertainment looked good but had to purchase conventional headphones to view.

Even though the weather made a lot of flights become cancelled Jet Blue made the flight that was supposed to leave at 9 pm and we left at 12:15 am and I was so grateful- Thanks to the Senior Jet Blue Staff who made those decisions

We were made to wait in the airport for six hours for a flight that was ultimately canceled.

Smooth boarding and friendly crew. Unfortunately as soon as we boarded the unit that provides air circulation failed. The pilot informed us and requested maintenance technicians to check it out. The plane became uncomfortably warm without any fresh air coming in. Plus the repair delayed our departure. I am glad the maintenance crew were able to fix the problem. I also was without use of my tv monitor for the first 1/3rd of the trip.

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

No knowledgeable staff at the counter or in a flight crew. No one knew why once flight landed at Philadelphia Airport then it took them 4 hours from runway to gate . Damn they took 4 hours to reach the gate . They messed up whole night for myself and for my kids.

Horrible communication about delay of flight and what options were available

Online check-in was not user-friendly. Too many fees, not cost effective.

FRONTIER SUCKS! The agent downstairs tricked me into booking, just to get to the gate. At the gate, they told me they couldn't help. I then called Customer Service. They and the gate attendants kept blaming each other. Neither side was willing to help the customer.

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!

Good for the price. My only complaint is that the pilot should keep the air flowing while passengers are waiting to getting out of airplane.

I arrived 1 hour prior to boarding, and they said I was too late for a domestic flight. First time I heard that :-(

Crew members are very rude and not cooperate with passengers.

Well, I didn’t have food! So NA wasn’t an option. I’ll be back!
