We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The WiFi was not working. That made for a long flight.

With Aeromexico it ended up good but with Delta it was bad because we did everything through Delta... Showed up at the Delta terminal... It was the wrong place! Nothing ever told us to go to the Aeromexico terminal. It said "in partnership with Aeromexico" but I was never instructed to check in with them or go to their terminal. We had to haul @$$ running through the airport and almost didn't make it thanks to this poor communication. 👎🏽

Absolutely no communication on why there's a delay and multiple flight time reschedules. I would have canceled the flight and drove back home if I known it was going to be rescheduled 3 or 4 times.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

I was in first class and literally the men behind me were so aggressively loud I moved myself to economy. This has become so common on Delta - people using audio without headphones, and men on 12am / late night flights drinking and yelling to talk to each other which prevents anyone around them from resting. Pretty crazy to have to move from first to economy (poorer service, less comfort...). Wild wild. Looking into other airlines.

Love delta smaller commuter plane so no entertainment and paid wifi on MKE-LGA leg was extremely unreliable and slow

Stop changing gates. Stop cancelling flights Stop moving my seat.

Extremely disappointed with Delta. They canceled flight last minute and then I rebooked the other flights and with which were delayed as well

Could not get my connecting flight boarding pass until four hrs before departure! Ver annoying especially since the staff could not explain why!

Everything was on time and service on the flight was great!

Wifi Bluetooth features for watching in flight movie was horrible. Screen kept blacking out no connection of sound although it said connected. Other than that smooth trip .

The 777’s economy seat’s legroom was more tolerable than expected. I appreciate the reclining mechanism which slides the seat forward to minimize cannibalizing the space behind. The food was terrible: very salty.

The travel company that you have on your site did me so wrong. I don’t know how it happened, but they put my son‘s name on my plane ticket flying to Vietnam. Along with his birthday. They would not have let me fly from Fort Myers to Ho Chi Minh City. I don’t think that I can ever use your service again. I typed my information into the browser along with my passport number and four days before I’m leaving I have to quickly search another ticket to fly out here.

Seats are uncomfortable. This has been a trend in the industry for decades. Trying to fit more seats on each plane to increase profits at the expense of the passenger.

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

It’s always a great time flying with united airlines.

Good flight. Efficient boarding and competent flight crew. No problems until we arrived at our destination gate. We were early so there was an aircraft at the gate that had to move before we could pull in. Then, due to the type of aircraft we flew, the cabin door could not be opened until some luggage from the cargo bay was offloaded to preserve center of gravity characteristics. So, that further delayed deplaning. Despite being 20 minutes early on landing, we ended up being 5 to 10 minutes late after all the delays.

Everything went well except the turbulence what no one have a control of but pilot and crew handled very good!

There was no WiFi available, there were mechanical problems with the plane and we landed at C 124, then the gate was switched to A 26, then all the way back to C126! For a 75 yo woman traveling alone, this was a difficult journey, indeed!

It would have been nice if American tried to care.

Delayed initially because they couldn’t print the flight details. Poor instruction on delay. When I got on the plane the flight attendant argued with me about whether my carry on would fit (it did, although she didn’t acknowledge that). No greeting (other than arguing with me) getting on or off the plane.

Beverage service was not good. Also just one service in 5 hr 30 min flight. No ask fir water ir anything beside one time beverage service.

They are always late and seats was also not having working charger

Broke my luggage and I can't get a resolution yet.

My flight to London from Philadelphia was cancelled due to weather.

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Long delays, lack of information about the status of the flight. The flight was delayed 4 times.

Everything about the flight was lovely. My only suggestion would be to offer a few more options of tv series from Apple TV or HBO.

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Flight was delayed, then undelayed, then delayed again. Gate was changed to the other side of the airport. Horrible seats with no screens. Spirit os truly awful, even for a budget option.

flight delayed because of poor staffing and organization - confusion from gate agents and flight attendant supervisors scheduling a missing flight attendant. flight delay 1 hr 30 min

I liked the quickness of the boarding process. Things were run smoothly and the staff was very professional. The overall experience was great.

Flight was delayed more than 3 hours, and the metro had stopped running by the time we got to the terminal well past midnight, so I was stranded, alone, with no way to get home until the metro started up the next morning.

We get stuck in the plane when landed during 45min and no communication from the crew People were listening to their phone and music out loud and nobody told them anything I definitely want stop booking spirit flight it is a disaster

When I arrived at the airport at 4:00 in the morning, I was notified that I "hadn't paid" for my ticket (I had paid and had a boarding pass). Then I was told that while I had paid, the ticket was $600 more than it actually was, and that I needed to pay that so I could board. None of this was true, of course, but it took 20 minutes, two crew members behind the desk, and one on the phone to clear up.

The flight was delayed by two hours, then by three hours. Then, at 10:01, a notification that the flight was back on schedule for the original time. I just happened to be getting on a train to go to the airport at 10 just to be extra early for the delayed departure when I saw the update come through. I got to the train terminal at the airport at 11:07. A shuttle immediately arrived and offloaded, but didn't show anyone on before speeding off. It was 30 minutes before another arrived. I finally got to the terminal and through security and to the gate just in time for them to tell me the door had just been locked. Flight closed. I had to wait until the next day to fly out. No or for a hotel, a meal, nothing.

The staff were very helpful. Definitely the stars of my experience. The seats were very uncomfortable.

Good: It was cheap and they got us to our destination safely. Not so Good: Gates experience with many, many nauseatingly (almost) threatening announcements about bags size and how much they were going to charge us if our bag was too big, even to the point of having a gate agent roaming around through the passengers eyeballing bags size and making people go check their bags in the sizers.

For a change, friendly staff at check-in and in flight.

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!!

Remind customers of the need to have passport or new ID for boarding.

Flight was canceled. Most upsetting was message from Kayak, stating that the flight was canceled and click with Kayak for details regarding rebook, refund details. THERE'S NO INFORMATION PROVIDED BY KAYAK EXCEPT THAT FLIGHT IS CANCELED. AND NOW THIS SURVEY TO FIND OUT HOW WAS THE FLIGHT !!!!!!!

The flight never took off and we spent 7 hours at the airport

Gate not determined until I got to the airport - hard to plan the trip to the airport.

Our flight was canceled. I will never use Kayak nor Frontier for travel again. The entire experience was a headache.

Frontier.. nickel and dime add-ons. Flight late, on time, late again, last minute gate change, arrival gate required a shuttle to the terminal. They sure keep you guessing.. if you like a little chaos and airport anxiety, this is the airline for you!

This is my second time flying with Frontier. My current experience was very favorable. The staff from the gate to the plane was friendly, warm and professional. The food options lacked in my opinion. This area needs some attention in my opinion.

First of all we hade waited 3 hours in the airplane waiting to leave. Second the return schedule was changed and it messed up my entire vaction. I won't buy never again another flight and recommend to nobody traveling with them.

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.
