25 mins late. The flight attendants were chatting and laughing loudly at the rear, which was rather unpleasant.

25 mins late. The flight attendants were chatting and laughing loudly at the rear, which was rather unpleasant.

The flight was excellent, the crew was super friendly. The only complaint I have is, 3 of my zipper handles were broken and there were 2 massive scratches on the back of my bag

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

Empty seats next to me - wish it had been for a longer flight!!

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.

KLM remains a quality flag carrier airline which maintains its standards whilst all their competitors are lowering theirs.

Cabin crew professional, polite and friendly, boarding was seemless, but come on KLM surely you can do better than a pack of cheesy biscuits as an inflight snack

Great boarding, great short flight but no entertainment whatsoever and no wifi. Prepare to disembark by a staircase.

The plane. Airbus A330-200. Comfortable for a 7-hour flight. Seats seemed to have more legroom. I was in row 17. Flight was operated by Delta but was better than expected.

I thought KLM was the best airline but the Lima - Amsterdam was 1 hours late, the Brussels - Amsterdam was 2.30 hours late and the Amsterdam - Lima was 30 minutes late

Terrible flight. 1. They’ve only one option for food. 2. Seats are very cramped and screens are tiny 3. No pillow or blanket provided on long haul flight

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

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

That was a short flight by the only time I could actually sleep

How can a national carrier and part of Lufthansa group not even provide complimentary water and a snack in such a long flight ?

Terrible seats. Whoever designed the seats should try taking a long flight in it themselves.

Food quality is deteriorating each time, last year was very good. I avoid the plane food lately.

Been flying on various airlines, all over the world, for 50+ years. The food on Brussels Air was easily the worst I ever endured.

my husband's monitor did not work. there was a visibly ill family in my husband's row.

They knew what the weather forcast was so should have put us through a tunnel we all got wet through getting on the plane so was cold all the way home also we were running around tge airport from gat to gate changed from 1 to other 45 minute walk each way people didnt know what was happening old people were ending up ill it was to much for them.

Got what we paid for. Food option. Need to carry more stock.

Usual slick event. All the basics covered well. On time, plane full.

The staff were lovely but the plane was very cold .

The flight departured two hours and a half later than the original time flight. We loose our bus and it cost us 108 £. We are not repeating

Has always great flight. You get what you pay for.

3 hours delay, little communication, no refreshments provided despite legal requirements

On time! The wait to board standing outside was miserable. The “priority” boarding is misleading as it does not help the boarding process at all. The bag charges were very high and my expected carry on did not quite fit in the measurement box. The lobby experience at the airport was terrible! Signage and directions were inadequate. The staff was all lovely.

Late boarding as our plane was late arriving from previous flight, then 3 hours sat on the tarmac waiting for a time slot. Then, when we arrive at Birmingham airport, we had to lug our bags down the plane steps, cross the tarmac and lug our bags up the stairs to enter the airport. Horrendous!

Sadly the experience with the airline is worse one ever. Starting from the state of the inside that was filthy that flies was flying around our legs. The food is expensive than a restaurant, imagine a family of 4 spending almost £50 for just sandwich of bread and ham no tomatoes and lettuce in it and a small container of crips that is not up to 20 pieces and a can of coke or Pepsi, and unfortunately that is a person ffour hours pay of work before tax. I know the blame will go to high cost of living but even at that the price is too much.

I ordered a drink, but never got it. I ask what type of drinks they had and they could not tell me and there was not printed copy that I could find that is usually on most airplanes. They served dinner and never walk back to see if any need a drink or anything afterwards until they served the snack just before landing.

Check-in wait time was quite long (understaffed for the volume of customers), but energy and hospitality of flight crew was great!

I really enjoyed the flight…and food and the hospitality but didn’t get the food I requested for.

Everything was terrific. Kevin, and the whole crew, were exceptional. Five stars all around! Thanks so much.

Flight held at gate for other passengers. We ended up being late and missed connection

Should have more cosmopolitan food choices - too many Indian dishes - the only entree not Indian was lamb which I don't eat

I have nothing but amazing things to say about every staff member I encounter on my transport from Brussels (Bru) to New York (jfk) via London (lhr) after many flight delays and changes every colleague I asked for help gave me the utmost respect and did everything in their power to make sure I arrived in Washington DC to make it in time for my brothers wedding. The flight attendants on the flight from Bru to lhr move me to the front of the plane so I could get off quickly and try to make it to my connection to dc, when I missed that wagans at the support desk did everything in his power to get me to dc via two transfers. Especially during the busy holiday season I am so so grateful for the amazing customer service that I encountered today.

Firing with British airways leaves me feeling stressed and disappointed. They are substandard in so many aspects of airline travel.

Worst trans-Atlantic flight in years! The seats were incredibly tight, both in width and depth. The back selection was so cold, it was like traveling in a refrigerator. Although I had an entire row, the seat arms would not go up, so I could not take advantage of it to sleep. However, the crew was smiling and helpful and really seemed to enjoy their jobs. The food was the worst I have ever experienced on any flight. The PA system blasts announcements to the point of hurting my ears when using the audiovisual equipment. Not safe or sat. Also, I did not like the bait and switch tactic. I put in a search with one bag and the other flights had put that into their price, but BA did not and made me pay extra for it which would have made the price comparable to others. Also, even at check in there was no “choice” of seat, unless you paid extra for it even in the same row. No other airline I have been on does this. Once check in begins, normally, you can choose any unoccupied seat in your category. These tactics and the lack of comfort means I will never fly BA again.

An early flight and a bit confusing where to check in with British Airways; good we asked at the information counter the night before as we stayed overnight at the Sheraton on the departure level.
