No wifi, seems to be very common with Southwest currently. Everything else was normal.

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

Friendly crew kept coming by to make sure all was ok, provide additional refreshments, etc.

For the first time in a long time we had a flawless experience with Southwest. Both flights were early and no mechanical errors at all. We were shocked and pleasantly surprised 😮.

it was great. the crew is exceptional. the flight was on time.

I stopped flying southwest a long time ago. I don’t care for their boarding process, especially when I have a family to try and seat together. The early bird check in made it so much easier. As long as you do that, it’s great.

Everything was very good. I will fly Southwest again soon!

Nice and easy. You can't go wrong with the value and quality or Southwest.

Flight was cancelled due to “inclement weather” even though all other carriers continued to operate as planned.

sw cancelled our flight 2 hours before we were to leave. Our bags were already checked. Only communication we had was a text that had a link to reschedule that did not work. When we finally got to front of line ticket agent said they could not get us on a flight until Wednesday. This was Sunday. 3 days. The. They stated since it was “weather” related they would not give us vouchers for food, hotel stay anything. So we had to book on a different airline costing us an extra $1000. Unacceptable.

It was hot and not as comfortable as the flight to Chicago. Must have been a different plane that needs to be worked on or replaced.

My flight was delayed so bad i missed u it so i just said never mind

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

Gluten free snack options and meals that offer both gluten free and dairy free.

The pilot was late so we didn’t take off til almost 2 hours late.

First class ticket gets you a choice of chips or nuts. . Just like economy Southwest. Also no screen in the seats. This is first class???!

All of the United employees I interacted with were professional and courteous. The aircraft was clean, the food on the flight was good. No complaints here.

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.

The United website was easy to use and had all the information I needed. I needed to change my flight and it was accomplished easily on line. I was also easily able to upgrade and for a reasonable price. Boarding went smoothly and the flight was in time. The service was good in board but the crew did not seem happy at all. Limited availability of meals - not much choice for purchase and in business class they ran out of one of the meal choices by row 4. .

Late boarding by three hours. No Wi-Fi. No screens. Cramped seats. Sitting on the tarmac for 30 minutes after landing waiting for a gate. Delay in luggage getting to baggage claim.

Delayed delayed. Poor professionalism. Our seats changed and we pay for them

WiFi didn’t work the entire flight. Very disappointing. Minimal food and options - sadly the state of current affairs. All other aspects of the flight were fine.

Given it’s a red-eye into Charolotte, we didn’t get any food. The survey does not include “N/A” so the rating will be skewed.

The plane was broken so we had to change planes.

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

It went up and down at the right time and place. I’m happy with that outcome.

Airlines must do something with overweight people... Maybe reserve a business class seat for them, or you could pay the consequences if someone overweight seat side by side to you in economy.

Flight was cancelled as I was in line for security. Next available flight got me to my destination 24 hrs later than the first. No refunds offered, just credit toward another flight. I booked with delta, got to my destination only 2 hrs behind my original flight schedule. Won’t be using American again.

It was a good flight - not overbooked and in time.

It was perfect in almost all ways. In fact it arrived early in both legs of my flight. The entertainment was marginal, but that was due mostly to the length of the flight. I love American!

Flight was delayed many times. The crew was friendly but you eleven had to buy headphones to access the movies in the plane. $8 is not a lot for one person but it is when you travel with all your family.

JetBlue is always consistent and great, the food is limited in selection, but at least you can grab as much as you want on snacks and drinks at the Blue Locker.

Very well organized both boarding and deplaning. Very satisfied with the service I received.

Flight was on time arrived at the destination 10min early they kept in touch via email

at the time for boarding the lady just call Group A and no other goups and everybody from A to F go inside without the right turn,and when we get in theres no more spsce for carry on , the ones that get in at not correct group from the back occupy our space !!!!! a mess !!!!

The boarding and flight were ok, but there were several painful issues. The flight was 3:20 in the air and almost four hours door to door, but they only had snack packs on the plane. They really need to have food on longer flights or make it clear to everyone that they won’t have food. They also advertise free WiFi, but it did not work for 90% of this flight. Again, almost four hours door to door. If I had known I was flying spirit for JetBlue prices then I would have planned differently.

I think the food / snack service was very poor. tehy could have done better. Evrything else was great

No wifi, not even while close to the continental US or Puerto Rico, no entertainment whatsoever (TVs not working). Totally disappointing.

Wifi screens were great. Both flights were delayed, spending all day flying home and then getting home at 3am ruins the next day also.

My TV was broken that was the only bad part. The rest was great.

During the flight I suddenly felt very sick, and no one from the crew even tried to help me or check on my condition. They seemed completely indifferent and showed no concern for my well-being. I was very disappointed by the lack of care and compassion. I hope the airline improves its customer service and trains its crew to respond better when passengers need assistance.

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.

The worst. They don’t follow procedure for boarding per group. Flight got delayed for no understandably reasons, they changed our destination from PR to Miami, left us inside a plane for more than 8 hours, then cancelled flight in Miami leaving us stranded. Poorly managed re-accommodation for a new flight and overnight stay so I have to spend in a new ticket and my own hotel room to been able to get to my office next day. Lost 2 days of work and as a doctor, patients loosing their appointments. to other flights and besides

Decent clean onboard experience. Okay discount airline experience. Unfortunately, any customer service interactions are difficult and unhelpful. There is no service. Also, a premium seat only gets you premium boarding if you line up first. Once they start general boarding you must go to the back of the line. Not very premium

The delay was ridiculous because nary a word escaped from the gate attendant regarding our flight status. It was a complete joke.

I liked the price of the flight and the chance to buy a seat with no person seated in the middle seat.. Also the flight was right on time.

Plane was down graded and I lost my uncharged exit row with more leg room. No mention or offer of refund from podium. Flight attendant was nice to explain this happens often and that I could request a refund via online form submission. I did this and have heard nothing back.

The flight left over two hours late. They charged me $180 to bring a carry on. There was an error with the spelling of my name and Frontair agent lied that I would need to pay $200 for her to fix the spelling, and pressured me that if I don't do it quick I would lose the flight. I called back and another agent said it costs $75 to fix. All in all, this company is a complete scam.

I took my first and last flight with FRONTIER. The seats are not able to be reclined so it’s not a very comfortable experience when you take a flight of 3 hours or longer. You must pay for your luggage either carry on or check in, so taking all this in consideration at the end what you think you’re saving your paying in services that should be included. Not a beverage in sight. . You’re seriously better off getting on a proper airline such as Delta, AA, United, etc.

Frontier notifying me earlier of flight delay of over 2 hours.
