I was given middle seat on this flight and prior Boston to Seoul flight That is a problem for long flights, Kayak system did not give me a change to select my seats and assigned me middle seats regardless of my elevated status in Delta. This needs immediate attention.

I was given middle seat on this flight and prior Boston to Seoul flight That is a problem for long flights, Kayak system did not give me a change to select my seats and assigned me middle seats regardless of my elevated status in Delta. This needs immediate attention.

I didn't take this flight. I changed the flight. Why am I getting surveys and notifications on flights that I change. Seems like a defect with Kayak.

Delta One is extraordinary. I fly business when somebody hires me. I just wonder why there is such a chasm between business class and the insanely inhumane and nonsensical coach. The seats are not large enough to fit even my tiny wife. We fly 10% of what we did because we don’t want to pay 5-10 k but for $400 it’s unbearable. It seems like the accountants took over and made stupid decisions. Screw in 20 extra seats and make it so unbearable that people fly 90% less. Just put the damn price up and put some proper chairs in. But business, yay.

Timing, quality of service, promptness and courtesy of the staff

It was last minute due to weather - considering - it was amazing! Good smiles, friendly staff and they were making sure we knew what was going on when and where.

delta last minute gave me a boarding pass for a different flight with no confirmation that they were changing it

The flight was comfortable and uneventful, which is what I desire

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

Excellent flight and got us around tough weather. Only issue was seat TV did not work and crew tried to reboot.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

Empty seats next to me - wish it had been for a longer flight!!

I’m grateful for the KLM Air France shuttle bus service to Ottawa. However due to construction and other issues related to the chaotic Uber pickup system at YUL, it’s a challenge to find the Kelios bus service to Ottawa. The signs are not clear or even available. No staff to guide passengers. It’s a stressful experience.

Flight was on time, staff are friendly and helpful onboard.

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Flight was ok but lack of communication cost me to literally beg to be put on another flight as connecting flight had departed

They forgot to serve food and the crew was very unfriendly. Never experienced such a bad KLM flight. Usually fly from Toronto. New York was different.

The immigration hall in Amsterdam was understaffed, so passport checking was slower than it should be for a major airport. They need to get the automatic readers up and running for non EU passport holders. Waiting in line after a long flight feels a bit abusive.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

Ad experience - been flying many years with them but they are losing out to other carriers with their service and bagage / seating policy. My 2 12-yo kids were not placed with the parent. Absurdity.

We upgraded to business class. Nice seat with lots of room but otherwise not impressive.

Delayed departure Madrid to Lisboa and my luggage no arrived

this flight was awful from pre-boarding to on the plane. There needs to be more coordination between TAP and My Way. We were in first class and I am handicapped. BY the time we got on the plane there was no place for our baggage and the crew did not handle the situation well. They gave us an argument and said that we'd have to have it checked. Then, after I complained they moved some people's bags to put our small carry ons several seats back of our seats which were in Row 4.

Late. Lack of updates. Rude hostesses. Terrible food. Lack of headphones.

Flight was delayed but crew gave little to no communication, then “began boarding” but really just had everyone stand up and wait for an hour without any news or updates, as if we were going to start boarding at any second. Total chaos. Seemed like this was their first time boarding a plane. When we arrived at our destination, we waited for over an hour for the baggage claim belt to even turn on. Probably waited at baggage claim for our luggage for close to two hours. Everyone was very confused and of course we all worried that the luggage was lost. Again, zero communication and everyone we asked just said “I don’t know.” So we were left wondering whether to wait, or file a missing baggage claim, or check the other baggage claim belts (which we did every fifteen-twenty minutes because we were just confused). Lack of communication throughout the experience was a huge issue.

The value is there, but the layovers in Lisbon were not great. The passport control was so bad that a 2 hour layover became very tight and on the return the Terminal was barebones which made it a long 3 hours.

From Casablanca to Lisbon our baggage 2 pound over they want me to pay $120 for 2 pound which unexpected we are two family 8 of us they counters lady her customer service is not good I fly frequently for my business next time fly with TAP Air I will think twice

Booked business with TAP from LAX to Cabo Verde - overall ok, but just doesn’t feel like business class. More of a budget airline

Poor. Our flight was delayed and they told me I would be fine to make my connection in Lisbon, I missed it. Then they told me my bag would be automatically loaded onto my new flight to rome. It wasn’t. It’s been 4 days and I still don’t have it.

I like the price. I dislike the website where I wanted to ask questions about the unusual high prices of the luggage fees. I called the toll free number from the United States and I cannot get through. You should test your own toll free website for info and you will know what I am writing about.

Excellent experience in every way, from ground crew helpfulness, boarding experience, inflight service all the way to modern equipment. My new favorite airline. I wish I could fly with them more often.

For a no frills flight this was surprising comfortable. The crew were helpful and nice. The flight was smooth and there were no delays or issues which I haven't had on a flight in a long time. I would definitely fly with them again.

The flight was canceled by play less than 24 hours prior to the trip, and I was unable to re-book. Have not received a refund for the trip despite filling out the appropriate form.

Was was cancelled less than 24 hours prior to my scheduled departure by PLAY. Despite my attempts to rebook my travel, I encountered significant cost increases that rendered this option unfeasible. In accordance with EC Regulation 261/2004, airlines are required to issue a full refund for cancelled flights within seven days of the scheduled departure if a refund is requested instead of rebooking on another flight. It has been three weeks without a refund or an answer

It would have been better to have USB charging ports available on the longer haul Flight that one of 2 hours

Was very good Staff was great. No tv monitors tho. So long flights make it longer

The worst. No free beverages. No entertainment on an overseas flight. Not enough space. Never again.

Play is affordable! Only way we fly from the states to Europe. Left late but arrived on time

have screens on backs of chairs...offer free snacks and water

The issue was not with BA it was with the link yoiu sent fopr booking the flight

Loved the boarding option from Business class lounge, experience on flight was excellent, plenty of good food choices

Getting the boarding passes between the BA and AA apps was very clunky.

The airline was not clear about a new departure time so we got to the airport early anyway. The flight left early which was great because of weather. The check in process was very easy and staff were friendly and helpful. The crew was great and our flight was very good.

Awful it always is unfortunately is the only way to fly direct to london

I travelled in business class and was disappointed by lack of service, curt and borderline rude time of the crew and to top it off, all of my luggage was delayed. It was like pulling teeth to even report the missing luggage and recover it the next day from the airport.

Plane was extremely delayed, but not all of it was BA fault (some was). Worst part was lack of room - this had as much space as an Allegiant flight. I thought transatlantic usually gave you an extra inch or two, but not this one. Entertainment system sporadically worked and didn’t have great options. Overhead bins are old and tiny, not as good as aunties new planes.

Boarding was poor. All groups called immediately one after the other resulting in a long queue in the jetty/jet bridge. Seats were very hard and and did not recline on a 4.5 hour flight. No food was available. Plane was cold. There was no entertainment.

The cramped seats are cruel and unusual punishment and may violate the Geneva code.

Check in was was and the agent was very friendly and helpful The lounge was nice...boarding was straight from the lounge Everything worked at our seats, and video entertainment was good ..food was mediocre
