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

It was just okay, no frills, basic transportation with no luxury. No screens on the seats, no water or drinks on a short flight. Full flight but at least it was on time.

The first time I flew in the extra legroom section. It was difficult to notice a difference. I had bad luck with my neighbors. The crew was okay. Southwest has reduced the live TV options.

No gluten free snacks. Seats felt worn or bare bones even though it was a new 737 MAX 8.

Plane was clean and comfortable. Flight attendants and gate staff were professional, friendly and efficient. Boarding and deplaning were orderly and efficient. All in all, the typical excellent Southwest experience.

Not having a five hour delay with little notice! The crew was very kind, though, and just as tired as we passengers were. The flight didn't depart until nearly 1 am...and no reason was ever given.

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

I have not flown Southwest in awhile and had a very pleasant experience. From ticketing to boarding to the flight. The flight left on time and landed ahead of schedule. It won't be so long next time!!

Our flight to Oakland was great bc the plane was new but it was delayed by 15min not bad at all. Over all it was an 8/10

The flight in it self was good. The delays looking for pilots was unexpected.

Love me some Delta. One of the few airlines to recognize and support veterans. Easy boarding, flight was on time and arrived early and the flight attendants were excellent on this flight.

We sat on the runway for over an hour before departure. That was unwelcome.

Enjoyed it very much. Especially liked the free WiFi that Delta offers.

On time flight. Seat comfort could be better in the Comfort section.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

The important things including boarding and the flight being on time and safe were excellent. The disappointment comes from the comfort and amenities. Was misled by the "availability" of inflight internet- there is an extra cost. The tray table was broken, the bathroom door stuck and flight attendants were competent but not very friendly.

Flight was delayed, missed connectingnflight to DC. Put me on flight to Baltimore, had to rent a car for $200. Plane was old, wall peeling around window. Flight was packed, every seat full on small plane. I spent 14 hrs on Friday in airports and missed my planned weekend event.

You could have not cancelled the flight (AA, which I will be flying from now on) left for BOS despite the fictitious weather issues (that no one in my Boston family could see). You could have rebooked my direct flight to another direct flight instead of sending me though JFK, the worst US airport after O’Hara You could have rebooked me on a Main Cabin seat (like the one I paid for in my original ticket instead of putting me a the last row on JFK->BOS leg, pocketing the difference in ticket price But I do not really care whether you will ever do that in a future because in a future neither I nor anyone from my company (unless they pay out of pocket) nor an of my clients and partners (if they heed my advice) will ever be caught dead on any of Delta flights

Temperature in the plane was quite warm for the entire flight - actually just outright hot making for an unoleay4 hours. Crew either couldn’t or wouldn’t do anything about it. No acknowledgement or apology. All passengers were commenting on how hot it was.

Airline stewardess service is good. The check-in attendant had a bad attitude and was unprofessional. We did not complete the trip as originally planned. Very dissatisfied☹️

The flight was significantly delayed. The inbound flight from EWR was delayed departing because of mechanical problems. My original departure from CLT was 5:28 pm but due to the delay of the inbound flight, after arrival, deplaning, cleaning, boarding, we did not push back from the gate until 9:00 pm. Once in the air, the flight was smooth and what was originally supposed to be an arrival in ORD at 7:30 pm local time turned out to be 9:35 pm.

My bags were misplaced!!! Im in a foreign country with no bags

Bad food, bad service, cold cabin with no additional blankets when asked for (they told me they don’t provide additional blankets). I’m a frequent traveler and this is one of the worst companies I traveled with (by the way I thought that I booked my ticket with Lufthansa but I didn’t see that the flights were handled by United).

Flight is clean and ontime. Crew is friendly. Snack can be better and the internet connection is poor

United airlines, mediocre at best. No issues , nothing great . Worked for me

Short and everyone communicated with me about the changes every step of the way.

The boarding process was delayed and the miscommunication of what seats are broken

After the morning frenzy of 35 min wait through CLT security at 4;30 AM, it was nice to have a smooth pleasant boarding experience. This 6:30 AM flight was not full. We were able to get seated swiftly and took off promptly. Nice touch they distributed the old fashioned headsets with 8 mm jacks. Snacks were decent and arrival was uneventful.

Flight from CLT to DUS via MUC ticketed by United Airlines and operated by Lufthansa. 2nd leg of flight from MUC to DUS was cancelled and no notification provided. At check in , Lufthansa agents at airport were unable to locate record and wanted us to contact United Airlines directly.

Airline did not explain reasons why flight was delayed two hours. Explanations were badly needed and rarely provided. Problem seemed to clearly be the airline’s fault and not the fault of the weather or airport.

Smooth flight. From the early boarding and all were on board before departure time and arrived early in ONT. Great crew. Thank you!!!!

Amazing I love American. I’ll never fly anyone else if I can help it.

Boarding was very efficient. Everyone got on board and we got on our way very quickly. It was frustrating that the entertainment app was not functioning properly. I was not able to activate some of the movies offered. The crew on this flight appears to be pretty grumpy. They had no smile on their faces. I felt like they were doing us a favor for being there.

Long 5 hour and 45 min flight and only one drink service and cookie snack

This flight didn’t happen because AA agents didn’t let us board the flight

Would have been good to have a meal since it was a 5.5 hour flight

Plane was good but was delayed. probably not AA fault but caused a 1 hour delay. Seating was cramped.

Poor availability of food. Cold cabin temperature. Extremely long waiting time for a flight attendant to respond to a call button signal.

Flflight crew were amazing, kind, and considerate. Fofood choices were limited, and didn’t have a variation.

I was hoping that the food would be a little bit more selection,, but I understand with the airlines what they are going through flight was excellent

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

Terrible. The canceled my entire flight when I requested a refund for a trip frontier canceled trip one way.

i was unable to check in the flight. refund requested

I think Frontier was very good at communication. Their app worked very well. Loading was great and the flight was nice and easy.

The crew was mostly okay. The flight attendant who answered our questions was curt and unhelpful unfortunately. He seemed upset and I understand having off days.

Flight was cancelled and was not able to get another flight thru Frontier. Per frontier a refund was issued but I do not see a refund on my Afirm account.

Horrible communication about delay of flight and what options were available

The agent at check-in was strident, unwelcoming, and condescending to customers ahead of me.

Was charged 99 dollars for a bag despite agents previously telling me it would be ok. Customer service was unhelpful

I will like you ( Frontier Airlines) to fly into LAX instead of ONT because I live in LA and the subway takes me to my house in just 15 minutes
