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.

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.

Worst airlines either. First leg was delayed because of crew not available. My connection was missed so they booked me automatically the next day! But, impossible to get anyone on site, web site does not let me access my reservation anymore, confirmed by useless agents over the phone. My 2-leg trip with part in business class arriving at 4:10pm ends up in an awful 3-leg arriving at 9pm the next day with no way to even choose the seats and of course at the very end of the plane. I can understand problems arrive but the way Air France handle it is just unacceptable. You are on your own. Apparently getting you to your destination is the only thing they consider their duty. The customer experience and fatigue is none of their concern. And I have a status with them. I will reconsider my priorities when flying with Air France and encourage everyone to do the same.

The flight to Houston the agents were not very helpful

Cree was organized and pleasant. Plane had good seating but as it’s a shuttle toilets hadn’t been thoroughly cleaned (eg. bins too full)

All good flight was 35 minutes early when arriving in Edinburgh

2000 USD for a 10 hour flight on the worst seats I've ever flown in.

Good quick flight on a small but comfortable plane. I'm 6'3 and had plenty of space.

Offered to check carry on to final destination. This is the most absurd thing in the world. I'm carrying on because I need what is in the carry-on. I'm okay with picking up at next stop but then I will be on much larger plane that can accommodate it. Also, if there is ever a change to your flight. Go to the airport and have the people there fix your ticket. Don't do it over the phone or online with United they screwed us up and ended up with flights for our last leg that took off before our first leg.

Once boarding started it was pretty quick. Food was inedible; cold and salty..

Some flight attendants were great others were cranky. Seats were very tight and sitting on an aisle was very hard as the carts and people walking constantly bumped shoulder and arm.

In Liberia airport 5 min before our departure the airport was closed for takeoff for 30 min. Upon arrival to IAH we didn’t have any available gate and waited taxing another 40 min. As a result we arrived for 1+ h later. The walkway to the passport control in IAH is about 1-2 ml long. After the passport control you have to pass the security check again. Only 3 out of 16 checkpoints were open and the line was enormously long. As a result, even though we supposed to have 2.5 hrs gap in between the flights we missed our transfer. United rebooked us for the next available flight early morning and provided free hotel and meal vouchers through.

The staff was nice, however boarding taking 2 hours. That’s insane. Overall very bad experience, a lot of turbulence and when landed in Chicago was horrible. I don’t think I’ll flight with UA again.

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.

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.

We waited all day on a delayed plane. More than a 6 hour delay which caused us to miss all connections and spend a second full day traveling. Also missed a day of work that i hadn’t planned on.

I liked the air hostesses, but no wifi was available for flight. my original flight was canceled and rebooking was difficult and no reason was given for cancellation. Business class cabin was nice and spacious.

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

3.5 hr delay leaving Pittsburgh, notifications for which were incomplete and untimely. Connecting flight was automatically switched to one requiring more than a 30 hour layover! After waiting in a long queue, customer service reduced layover to 11 hours and also set up an earlier standby. The standby had empty seats, but the gate agent couldn't change our tickets! On top of all that my luggage was lost and has yet to even be located, much less returned 5 (FIVE!) days later. Too bad there's no rating below poor.
