Outstanding even though the 330 was one of the oldest in the fleet. The difference was the attentiveness and responsiveness of a really experienced flight attendant. For airline food great variety of interesting choices and good tastes supported by a good wine selection.

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

There were no charge points for phones on the economy seats. The seats were comfortable overall. Food was okay.. flight was on time

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

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!!

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

Everything was better but france airlines more better than them

Good leg room for people of all sizes. Pleasent crew.

WE didint profit of food , but for the other think all was good

Spacious and clean aircraft. Good food. Economy will always be squeezed but thankfully I had an aisle seat for stretching exercises. Good selection of movies, particularly Spike Lee joint.

Unfriendly, 8 hours delayed, no lounge access even flying business. Don’t fly Brussels

Flight from London was delayed so missed the connecting flight. Taking 2 days to get to destination which should have only taken a few hours.

Too cramped up for the better seats I paid for.

I didn’t like my seat in my return flight from Montreal to Orlando at all; considering I paid extra for better seats. That middle seat was cramped up way too much.

Suitcase didn’t arrive to Stockholm. Chairs y comfy and not even water is offered

Bad baggage and people management at boarding forcing me to dispatch my bad despite being the perfect size and respecting everything perfectly, whereas many did not and many free empty spots on the plane as usual… making me loose time and my planned bus at arrival to go to Geneva. Costing me 100 euros extra! So Brussels airlines needs to refund me

Boarding was terrible. We were all cooped up in a small, claustrophobic space awaiting to be let out to walk to the plane. Very cramped and very uncomfortable.

Although our departure (DUB) was slightly delayed we reached our destination (LBA) ahead of schedule. The price was very competitive too (around €100 return). Plus, the departure times for both legs were very good: 13:05 and 15:10, respectively. I gave a neutral rating for Food and Entertainment because I didn't avail of either.

Dislike standing for 30 minutes waiting to board. Coffee disgusting, hot sandwich almost inedible. Staff cheerful. Flight early.

Notified as to why there’s a delay with our flight.

Easy short trip from Faro to Cardiff. Exceptional staff. Early landing and straight through airport in 15 minutes from touch down.

Food and entertainment were not available, so my rating on those items isn't actually correct. There should be a "Not relevant" or "Didn't use it" option.

Delay in boarding with no explanation why. Stood for about 40 mins waiting to board

Rubbish moved my seat don’t know why same seat configuration cost me extra so me and my wife could sit together now I know why no paper ticket so they can do this

Slow and delayed boarding, including standing outside 15m in -3 temperatures, Late take-off approx 45 mins Very slow bag delivery approx 45 min - no explanation

The flight boarded nice and early and this meant there was no sudden rush at the gate. The only down side was the cabin was very cold 🥶

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.

The plane was a long way from departure lounge. The plane looked tired but got us there.

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.
