Good food. Excellent crew service. Clean aircraft. Narrow seats and isle.

I tried to upgrade to premium economy anis seat online during the checkin process. The payment didn’t work due to a technical glitch on KLM’s website. I wasn’t able to change my seat unless I called Amsterdam. Since I was in Canada and there’s a time difference this wasn’t practical. So when I arrived early to Ottawa airport my seat wasn’t available and I could only get a middle seat in premium economy which isn’t great. These middle seats are priced at the same rate as an aisle seat which makes no sense.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

Transavia flight. Couldn't select seat or anything prior to flight. No connection with klm systems. Seats are very crammed. Extremely no frills.

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

Flight left a few minutes late, but that's it. I wish the seats could be wider and recline more.

Overall a very pleasant flight. No significant issues on either flight. Amsterdam airport is very convenient for connecting

The IFE was quite old, but it worked fine and the content was good. The cabin crew were excellent and the food was as also very good

It’s chaotic at the bus stop outside of the airport because of the Uber meeting point. You need to be alert and look for the KLM bus which is not branded or labeled. Incorrect information was provided to go to gate 28, when in fact the bus was at gate 27. On the plus side the bus left early and arrived early to Ottawa.

Great flight because I upgraded to Premium Comfort. Made a huge difference in the experience.

riding in first class, you don't expect every time you order your dinner or breakfast that the first thing the stewardess says is Let me see if we have any left. Also, the food selection was not great: 3 of 4 entrees had mushrooms and I dont eat mushrooms, the 4th item was 'let me see if we have any left' and this was within 30 mins of entering the flight! Same experience level, it didn't feel first class this round.

Boston to Doha was great but Doha to Dhaka was the worst experience.

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Overall experience was OK. Seats were truly uncomfortable for such a long flight. Food quality was mediocre at best. The staff was great though!

Fly Qatar Airways is always amazing. Their service and care for details is really very good.

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

Don't be afraid if you board an Oman Air Airbus A330 - it will take you to Colombo and not Muskat. The Aircraft is leased by Qatar Airways ;-)

Not good. Expected a lot more as far as excellence.

I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

The flight isn’t great, as the plane has faulty with light and noise. It blinks and make noise for 8hrs non stop! Causing health and sensory issues! Causing Hazard matter to all 3 babies that on bassinet seats. This matters affected 12 passengers and the most horrible flight I ever experience. Have been flying with MAS for more 30yrs and this is the worst! Very disappointed

AC not working, just slowly blowing room temperature air. Long taxi time does not help as well. Sweating all over the whole trip.

Did not take as cancelled 3 time so took another airline

It was a 2-hour flight so they didn't have much time for serving food. There was some turbulence so they could not serve hot coffee or tea for the safety reason. Good service, good tasting food, nice plane, a little bit of delay.

The IFE is quite unconvenient if using our own device. Not all passenger brought their own earphone/headphone.

Ok, but legspace on MH0127 from Kul to Per was too small. It was not possible to tilt my seat which I don't understand because the seat in front of my could do it. So I didn't rest on the flight. Also, the crew was probably understaffed because it took very long time to take trash after the meal. Everything very different from the flight with Malaysian Airlines from London to KL.

Service / food has to be much better. Staff were not very attentive to requests. Requested for a second serve of coke and got a weird look back from the host! Was also told they don’t have extra water bottles when I requested for one before sleep! Dinner time food was very minimum and average.

An overnight Doha to KL. Great sleep, good service and tasty food in business class

chaos boarding. Crew in business class seemed short staffed and lacking in attention to details initially, but did improve during flight.

The cabin was quite noisy as there were lots of children travelling for the school holidays. Found the selection of movies limited.

No entertainment and the seats are well worn.! To the point it feels like your sitting in a bowl

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Everything was fine except not posting the gate number until 14 minutes before boarding. In an airport the size of Heathrow, that was unacceptable.

We already had a five hour layover in London, and then they cancelled our flight about half hour before we were due to board. They wouldn't give us access to the lounge and hanging around the extremely busy terminal for another three hours until our next flight was crappy. 8 hours in a busy terminal is awful. The least they could have done was give us access to one of their quiet, comfortable lounges for the inconvenience. I heard from others that they do this a lot -- cancel these short flights if they're not completely full. When we got onto the next flight it was absolutely packed and uncomfortable. Just very disappointing. British Airways used to be a great airline to fly with, but it doesn't feel that way at all now.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

They took good care of me on the plane and had it not been for handicap assistance I would definitely had missed my connecting flight . Not BA fault but The airport security instead . Two hours is way too long for security

The least comfortable business class seat I have encountered for a while - very very firm when reclined making sleeping difficult. Cost cutting is visible everywhere - no offer to refill drinks (the wines were not good - so no real issue there :) ) Just not worth what BA charge

old seat need to go! outdated and uncomfortable. I waited 40 minutes for my bag

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.
