It was a pleasant surprise to have complimentary Wi-Fi on the flight

Communication doesn't exist. If you have any issues nobody will help you. I was told that the supervisor doesn't want to talk to us no matter what we need, so if you have a problem that's your problem. And the website doesn't work also, even to pay in advance for the first baggage fee. People with handicap needs of assistance are in a very bad situation also, because one single person has to handle two or three wheelchair at the same time, running and living you alone literally at the airplanes door waiting when even the pilots and crew members are already living and about to close the gate and you are there waiting for someone to show up to take you in a wheelchair to where you need to go, and some employees are nice and still trying to help you, but is hard to them to hand to much, and others are just very rude, and even told us that they are looking for better jobs. The food wasn't enough for all the passengers and the ones like us on the back of the aircraft had no choice but accept what of left doesn't what it was because the people of the front took most the food. The delays were everywhere and people walking gate to gate to find where they should go for checking, but nobody knew anything because they changed everything on last minute. You, the passengers, have nothing you could do about nothing, even when you told them that the rules and regulations says that if that is a delay more than 3 hours they should pay you for that, but what they gave us was only 12 dollars for me and 12 dollars for my daughter, two handicap people after all these troubles, and after we had the need to beg for water and food. Everything in our trip was just terrible 😕 😪 😩 from the beginning to the end when the people that suppose to assist us with the wheelchairs left us in a isolated spot where we should wait for Uber to pick us up, in the meadow of the night due to the flight delay (departure was 7:55 PM, MCO to Logan, and was delayed until 12:45 AM, when we were already waiting for our connection for more the 3 hours from the previous flight from GRU/Brazil with Latam, the worse carrier ever). But we did accept the voucher for food and again they left us at the court food at the airport and we had to call them to go there and pick us up otherwise they would not even notice that we would being left behind. I don't really appreciate anything 😕 and I felt disrespected disappointed and very frustrated because nothing worked even before on the website, the phone calls, and the rest I already told you.

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

Crew was nice, meal was good. Entertainment had to be rebooted 3 times and still did not work. Turns out there was residue on screen, it needed to be cleaned to prevent the touchscreen buttons from continuously activating. I had entertainment for the last 45 minutes of a 5 hour 45 minute flight. Really unacceptable for first class. Flight attendent indicated your cleaning solution creates this problem. Seems as if this is widely known, you should be using a different product or cleaning better. Really really disappointing which simply added to the wi fi on your planes with reliably never ever works.

My flight yesterday evening was delayed 3.5 hours with no water or food service. Poor experience

The tray table was broken and the food was terrible.

Everything was great until I lost my water bottle and they can’t seem to locate it. I know I left it on the plane though.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

Flight late, the waited for a long time for “personal” to arrive at gate to dock the plane in Rochester. So annoying. This flight was expected, why aren’t personel available for the jet bridge?

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

It was really nice journey i personally recommend klm flight

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

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.

Delay on my previous leg, had to run to catch my flight. But that happens. Overall ok.

Delay and had to run between flight to get my connection due to this delay but besides that the overall experience was ok. I arrived with just an hour of delay.

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

I love Air France. This was another great experience despite a slight delay in the departure. The time was made up on flight. I would take AirFrance again when traveling to the far East. Merci beaucoup.

Everything is good except the seats are tightened no rooms for the legs,

The flight crew was exceptionally friendly and helpful. Also the seats were comfortable and roomier than many other airlines.

Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

The boarding was efficient. The entertainment system was a bit unstable but Air France has a good selection of movies.

They lost my bag and I still haven’t received it yet

Communication on the delay, rebooking and how to get a hotel was poor. Mails, airport check-in and transfer desk said different things.

Safe and stable made me sleepy and I slept and dreamt 😂😂😂😂

Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

The crew was excellent. The food was not good. I have taken many international flights and the meal was not good by comparison.

On the seat map for this flight with TAP was shown a business class configuration of 2 rows/8 seats. To my surprise, 4 rows/24 seats being the middle is kept empty, old European type. I chose seat 2F, the the leg room economy dimension. This is not what I paid for. Disappointed!

Boarding felt a little chaotic as everyone was waiting around the gate. Food was great, service was good.

On both flights, TAP Air Portugal messed up the seating choices that I paid for. They acknowledged that I had purchased seating, that they were errant in ensuring my choices, but told me nothing could be done about it. When I asked to be refunded, I was directed to "talk to someone from Air Portugal" Mon-Friday, and then I was dismissed. No help, no phone number provided to me. I was very annoyed both times and feel cheated.

Flight attendants in business class were rather indifferent While in second leg operated by Portugalia TAP subsidiary were outstanfy

Business class seats aren't comfortable. Food was not good.

Great service overall. One of the best international flight experiences Ive had.

Chaotic boarding with no announcements. Carry on luggage needs to be checked. Bare minimum zero frill flights. Not a whole lot of anything positive to be said .

We were unable to check in due to technical problems on TAP’s end. The flight was delayed forty minutes with no reason given. We received timely notice of the flight delay. We were also notified of a gate change. The new gate was at a different terminal. When we got to the new terminal, we learned that we had to go back to the old terminal first to check in. This information should have been included along with the gate change notification. Also unexplained, the steward skipped us when offering breakfast.

It poured rain, our luggage was sitting out in it uncovered on the transport cart while our plane was delayed! Nice business class plane for short flight to Lisbon, but more delay & rain in Lisbon, with terrible Business class seat with no entertainment & cold food on longer flight to London…ALL LUGGAGE AND CLOTHES INSIDE THEM WERE SOAKED THROUGH!!! Could only try with hair dryer to get some drying before quick turn round to train trip.

All good, professional service, and arrived close to on time.

It's hard to tell where to plug in electronics, and the port on my seat didn't work. Their entertainment system was down. Vegetarian food options were tasty. Friendly, helpful flight attendants.

We loved our flight attendant (Emma, from Scotland), the meals were perfectly spaced out, and the in-flight entertainment was super generous and delightful.

Cancelled flight and re booked seats were a downgrade. British Airways said the upgrade was t available but when I checked it was but then they wouldn’t make it right

Flight attendants need to come by a little more often to pick up trash.

No WiFi. No food. 250 ml of water only drink option. No entertainment options. Extremely bare bones flight

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

Flew business- but plane was dirty, food horrendous. Too many business class seats diluted service levels overall.

The check-in baggage belt was broken (which is understandable) but what was surprising is they would check you in, give a baggage tag and then you have to drag the baggage to a different counter at the end of airport. No vegetarian option in in-flight meal. British Airways remains the worst big name airlines and always my last option while booking.

The to flight was excellent but the return flight the seats seemed not cushioning enough.
