Late FA meant slow boarding. WiFi did not work. I’m a medium plus sized passenger. The seatbelt was for the first time ever barely fitting. And we delayed on the tarmac 40 min

Late FA meant slow boarding. WiFi did not work. I’m a medium plus sized passenger. The seatbelt was for the first time ever barely fitting. And we delayed on the tarmac 40 min

My husband and I had boarded the flight from Denver to Chicago, and one of the last passengers to get on the plane opened the overhead bin above my husband's seat and threw his bag out of the bin to make space for his own. He said, "Mine is bigger!" The flight attendant supported the new passenger. They didn't care that my husband has two artificial knees and must have the foot room in front of his seat to be able to fit his legs in -- and to be able to stand, much less walk, at the end of the flight. I have never seen this happen before, and it was a disaster.

Terrible. They wouldn't allow me on my flight on the 14th..

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Excellent flight. Boarding was efficient and departure was on time. Smooth flight with on time arrival. Deplaning was also efficient.

Our flight was understandably diverted to a small regional airport in Laramie, Wyoming due to weather conditions, which I fully recognize and appreciate. However, the low rating stems from the experience that followed: passengers remained on board for over an hour without the option to deplane and stretch, despite the aircraft being stationary. Although the pilot opened the cabin door, only he was permitted to exit. Meanwhile, passengers grew increasingly uncomfortable as warm summer air entered the cabin through the open door, and being in the second row meant we were impacted immediately. While the flight attendants made efforts to keep everyone at ease, I believe allowing passengers to deplane briefly, given the extended delay, would have significantly improved the overall experience.

I never flew. Flight was canceled. DIA worst airport in the country. Avoid at all costs.

Very rough getting into denver. my kid threw up it was so rough.

Why wasn't this flight departure scheduled eith another crew so that it could leave on time? When we arrived in Denver we had so little time between flights we had run to the connecting flight. We should received some credit for the inconvenience.

Mostly good. Flight was crowded but Airline personnel were very friendly & accommodating. It would be good to have savory snacks rather than just sweet Biscoff cookies.

It was a typical flight. We had a delay which seems to be the normality now. And we had no in flight service due to conditions.

Flight attendants on this flight were very attentive and friendly

After we landed we sat on the tarmac for 1.5 hours waiting to get to our gate. Ridiculous.

the trip to madrid was uncomfortable with my legs touching the seat in front of me

The plane was late, when we did board the plane was as cold as a freezer. I was freezing the entire flight, no blankets. Lost miserable flight I’ve ever had.

Flight, food and crew were all good, friendly and very satisfactory.

Terrible. Flight delayed for more than 8 hours with only a $12 meal voucher provided for the inconvenience. The airplane did not have breaks on arrival yet they still made us go through the motions and board on time knowing we could not take off then sit for 40+ minutes before having to get of the time. A complete waste of my time. I cannot believe they can stay business with these shenanigans. I’ll avoid this company like the plague moving forward as the lack of accountability is disgraceful.

This was the best 2 flights I have had with American out of SGF. Great crew both flights.

We were delayed for a “couple of maintenance issues.” They were resolved rather quickly but a computer glitch caused someone in the airport to have to bring a physical copy of the paperwork so we could leave. I don’t know where they had to drive from to get to our plane but it took forever & we were 1 1/2 hrs late in leaving. The flight itself was fine.

Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

Too cramped up for the better seats I paid for.

I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

I never board the flight. My visa was delayed and when I tried calling Kayak, no one answer and I still have not heard from anyone.

All great. Very efficient. Good emails that kept us in the know

Original flight was canceled, booked another one and find out when checking I was on the waiting list. Horrible experience

Actually this is my first time using airline I was in every single thing that happened throughout our journey, the appearance of the plane inside furnished about the seating the flight attendants and many many more I was so excited throughout thank you Brussels Airlines for the great service.

On board service was decent. I like the legroom at UA that seems to be more than in other airlines

Give yourself over 2+ hours layover because if flight is slighlty delayed and you miss your connection, Lufthansa will do nothing for you

We would have missed our connection from Munich to Boston but we had a van outside the plan that wisked us to our terminal. Much appreciated and we didn’t even realize that Lufthansa had done this until the announcement on disembarkation. Well organized airline! Will definitely fly Lufthansa again!!!

Everything went well. I will fly with Lufthansa again. And use Kayak whenever I book flights

Bought a seat in a flight that got changed out so ended up paying for a seat I would have had if I hadn't paid.

Food was poor quality and the screens for entertainment didn’t work properly

Food was much better than my outbound flight. On-time. Good service. I had a problem with my entertainment screen, but the attendant fixed it promptly.

I think they overbooked Frankfurt to New York and bumped me off. This changed my return travel I arrived home about 4 hours late. Almost 24 total travel time Totally unacceptable Would not travel with United

United lost my travel information and canceled my original flight. I had a seat assignment but was refused the booking. I had to prove that I went to Germany on United Very concerned about security that no one recorded my passport from Cleveland to NY and NY to Frankfurt I arrived at home at 12:30am on Saturday instead of 8pm I expect a full refund from United Please provide information to assure compensation

I paid for extra legroom which made the long flight very comfortable. Food was very tasty, they fed us 2 meals plus a cookie snack and extra liquids. Checked luggage is expensive.

Lufthansa is turning into a budget airline. On transfers, the luggage never arrives if you have less than 2 hours for the transfer. This is happened to me multiple times when I end up on flights serviced by Lufthansa. The first leg of the flight was serviced by Discover Airlines. It was a 3-hour flight and they only offer a glass of water. Everything else is for purchase. I purchased my ticket as economy which should have included a bag but it ended up booking as economy light so I had to pay for a bag in each direction.

It was good although our flight to the UK was cancelled and rescheduled for two days later. This was after we were already seated on the plane. We missed the first leg of our trip. BA did put us up at a hotel and paid for our meals but we lost our hotel costs in Glasgow.

The crew was very nice and pleasant. We were very reluctant to book our flight with British Airlines because we had bad experience with their flight attendants on the previous trips, they were rude and not helpful.

I am a 25+ years American Airlines member. British Airways is simply above and beyond in every customer satisfaction category.

The seat pads are past there sell by date now and are uncomfotable. Also, with screens in the back of the seat, the seats shouldnt be able to recline as this puts rhe screen in your face.

1. The website didn’t allow me to checkin from London as I have Bangladesh passport with US permanent resident card. This pushed me to sit with my wife in the middle of two aisle seats, terrible experience! 2. BA should allow within 24 hours to checkin with other passport holders to choose better seats. A 2nd verification of travel documents can be done at the desk about immigration status. 3. Food options were poor for vegetarian passengers, try to introduce healthy options avoiding carb-dense food ingredients.

Cabin crew lovely and accommodating and I'll always fly BA in the future

It was perfect. The service was exceptional. I would never want to cross the Atlantic in anyone else's sardine tins.

As I have said it sucked, the ticket counter to have to find and pay for another airline to get home. Now I understand this happened over the weekend but they should have someone there to talk to us instead of throwing the regular crew under the bus.

Everything excellent except for bag drop off. We started at the D area and that was so slow that it was eventually closed just as we were about to go to a station. We then went to F. We got one suitcase checked and then the screen showed that the station was no longer operable. There were long lines everywhere so we had to ask if we could butt in to the next station to finish. Again, this was the only incident, otherwise it was an excellent flying experience

Adequate to good experience. Comfort was mediocre but everything else was good..
