Brand new plane lots of room the snack was very flavourful and enjoyable

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

The flight was delayed. The aircraft was unclean. Promised seat was not given due to change in Aircraft. Not one crew on ground was in a position to give any response. Amsterdam Airport is AVIODABLE Over crowded. Over Expensive. Poor Services.

It was really nice journey i personally recommend klm 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.

Terrible last row seats many seats available but no offer to move to better seat

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

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.

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.

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.

Not consistent with the food quality (I mean taste not freshness)

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.

Couldn’t get boarding passes online, delayed an hour, and smallest amount of space on board I’ve ever encountered for such a long flight.

Horrible seat at the back. Crew was very kind. Packed plane. Wordy pilot bragging about Iberia being punctual when many of us came from Alicante flight that was delayed an hour and many lost connection and we lost our luggage. Still waiting for it

Boarding was a mad rush as people still had issues with boarding passes and groups 3- 7 were asked to board when travelers were still stuck behind the document check. Food was one of the worst I’ve ever had in an Economy flight. The crew was very friendly though

Flight was fine - however my husband's checked in case was damaged, and mine still has not arrived

The boarding procedure got confusing because they wanted to weigh everyone’s carry-on. Apparently mine was 3 1/2 kg over their limit. I didn’t know they had a limit. And at the check-in desk, nothing was said about this. They wanted me to check the carry-on at no charge and that would have been fine except then they told me at my connection in London I would have to go outside to baggage claim retrieve my bag, and then recheck it. In other words, they could not check it to my final destination, only to London. I told him this was unacceptable so after a few minutes of discussion, they came back and said that my bag would be OK to carry on the plane. It seems that if you have a connection then the weight is not as important. Then when I actually went to board the boarding agent said I needed a tag indicating that my bag had been weighed, even though she had just five minutes ago talked to the same person who cleared me. Lots of confusion seems like a very bad process. They need to improve this.

My flight being automatically moved messed up my travel plans, and I had to quickly find an alternative mode of transportation. I couldn’t get a refund from any of the companies involved. Kayak, Ibiza, or Vueling. I am still unsure of how to settle my concern.

It was fine, older plane with limited entertainment, otherwise fine.

It was budget airline Veuling, even though we booked Iberia.

The staff was very nice and helpful. Some of the best crew I have met.

I've taken British Airways before and it has been great. On this trip to Spain and Portugal we had two BA flights. On both flights we were taken by bus from the terminal out to the plane on the tarmac. There were many older folks on these flights, and to ask people in their 70s to lug their carry-on and personal items up the long mobile staircase to the plane entrance, is very disturbing. I won't be taking British Airways in the future. Many people on these flights were very unhappy.

Good was great. Some of the older crew were grumpy and not customer friendly.

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

This was a special trip so we booked first class. It was obviously an old plane as the seats weren't that comfortable or spacious. We were delayed 45mins taking off as the "little engine that starts the big engines doesn't work". The powered divider between myself and the next seat in first class didn't work and my electrically powdered seat didn't work so I had to move seats to try and get some sleep. Food and drink were good, crew were great. But I'll never fly with BA again.

Service and food was amazing. Aircraft configuration is weird - stare at a stranger at take off and landing, during flight someone is crawling over your seat. It was lame.

BA Canceled this flight and put us on a flight leaving Aberdeen at 8:00 PM, delaying our return to the states by a full day. The cancellation caused us expenses in both Aberdeen and London and BA was completely unhelpful on the phone and at the airport.

First time flying with them! Loved it! Specially the schedule from Miami and being able to come back directly to New Orleans :)

They lost my luggage on my way to Namibia (I was unable to review that flight as I was in the bush/off line) It took 3 days to get my bag and I had to pay $375.00 to have it transported to my location as it was over 100 Kilometers from that Airport and the local Airlink carrier would not got that far.

Unable to check in online until the morning of flight. No early baggage check available nor any BA personnel present. Poor customer service.

Boarding process was chaotic. Confusion over Boarding gates: gate 55 or gate 56 ???. Unnecessary standing in long lines to board. Better to call out Boarding groups one at a time and everyone else to sit. Airline only has 2 Boarding groups 1-3 and 4-9. That causes over crowding and chaos

Lady next to me was coughing profusely the entire flight, other lady moved seats because of it, 8 hours of that during an overnight flight is a bit much.
