The flight was 45 mins late leaving, we sat without a/c for some of this, 2nd Meal was a slice of pizza. Movies were good.

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!!

Short flight so it was okay. Nice crew, all very pleasant and professional. We were near the back in row 27 so just as we got our drinks, we started our descent so had to drink very quickly!

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

Our first flight was delayed so we missed our connecting flight. However it was easy to book a later flight on their app.

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

The flight was great, the only reason for middle scores on entertainment and food is that it was a short flight so not included (but snacks were served including alcoholic beverages free of charge). I would definitely recommend KLM.

Was trying to change a flight but told that Canadian and local klm systems do not interact so they could not access my booking. Overall I like klm a lot but if it was important to change flights I would be very frustrated.

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.

The workers checking passengers from the boarding gate stole money from people whose luggage was perfectly fitting inside the carry-on sizer.

Whole way through - far more professional and slick than I expected

Good news was that Bag Check was open two and a half hours before the flight, which is essential with the chaotic immigration process. Flight was okay, but sitting at the back of the aircraft, 3 overhead bins on both sides were filled with crew bags and other misc items, so we couldn't put our cabin bags anywhere near us. To add insult, twice the crew managed to drop items that they were taking out of the overhead bins onto my wife's head, who was sitting in an aisle seat.

You need to make signage at Berlin Airport clearer. Having checked in online we had our boarding passes onlour phones. You do not make it clear that you need to check in again to receive a printed luggage tag. You get to baggage drop off and it says you can only do it with a luggage tag BUT not how to get this.

It was good except they could offer free water and tea/coffe

Sat at rear of aircraft and was very cold. As a frequent flyer for many years, this is was the coldest I have ever been. Other passengers and some crew were complaining how cold it was. Sitting near the doors always risks being colder, just the way the aircraft works - but this was exceptional, bring a good jumper. Everything else was pretty standard easyJet - good value low cost carrier.

The plane was postponed for over 2.5 hours, which meant that all four of us missed the check in time for our ongoing trip to Melbourne. We had to buy new tickets for 4 people as we had to forfeit the ones we had. The cost was really unfair. i understand that it was snowing during the first leg of the plane for that morning. Surely the cost could have been shared by the airline and not all by us. I could have bought insurance - but you can see how much I travel. I will need to chose more trustworthy airlines.

The true is that travel from London to Faro on 11/12/2025 by BA was cancelled, so I did not go to Faro, so i did not board easy flight. The mediocre qualification to you was because even when i bought an insurance, i could not change date neither obtain reimbursement. It could be ideal if you do something in order for me not to lose the purchase Thank you

Queuing for quite a while despite using the "speedy boarding".

Not great! Rude staff in London and the worse baggage reclaim I’ve ever seen. Great staff in flight but doubt I’ll fly with them again

I have noticed that the airlines, including this flight, pretend there is going to be turbulence, announce such, and say they can’t do beverage service. There is no turbulence and the seat belt light goes off 10 minutes before they ask for tray tables up and seat belts back on. They are just trying to spend less money and it’s quite transparent

I enjoyed the flight. I did find it strange that when I arrived at my seat although I had paid for a window seat that I was assigned a middle seat. Thankfully I was between a couple and they wanted to sit together. Please do a better job with this BA!

Flight was fine, food much better than anticipated, and flight attendants were helpful and friendly!

The lack of organization at the boarding gate was shocking. It was impossible to determine where the line was and it was hard to understand the announcements. It was so confusing that my wife wanted to get on the wrong flight. I am also annoyed that BA is adopting the sleazy policies that the budget airlines invented of charging extra for even the first checked bag or choosing your seat.

My flight out of Miami was delayed by 2 hours which meant I had to quickly make other arrangements for pick-up in Glasgow. A $9 voucher for food was issued. That’s not much of a gesture in my opinion.

We were never contacted that our flight from Glasgow to London was delayed. Got to airport six hours early to find that we were going to miss our connecting flight to BWI. Our flight is scheduled for two days later and they only gave us a voucher for one night hotel. E we’re delayed on the front end too and had to fly to Edinburgh instead of Glasgow arriving six hours and taking a $200 cab!

The crew were very friendly and helpful. Also, the airline was very strict and not very helpful when I wanted to start by boarding from Heathrow airport instead of Glasgow international airport. I stayed 10 hours in the airport and no hotel or any form of compensation was provided. That sucks.

Flight canceled two hours beforehand, BA reticketed us so that we would have had to leave from Edinburgh instead of Glasgow, where we were already at the airport. We would have arrived in Boston too late to get home to Vermont. Instead with some pressure we were reticketed from Glasgow on Lufthansa, which avoided Heathrow, a great benefit after our horrible experience at Heathrow when we arrived in Britain three weeks earlier. (Kayak assebled an itierary that did not leave adeqate time for the connection at Heathrow, where thousands of people were trying tio get through inadequate and badly staffed security and staff did not know the slightest details about where and which lines we should get in.) The British Airways travel experience is not to be recommended these days.

My selected seat ending up being very uncomfortable both major flights. SFO to London and back. Seat arms did not go up so it was not like suggest by BA staff. On return flight my seat had a life raft barrier in front off me and large man beside me.

Crew was great. Flight was quick . BUT boarding was outside, down and up steps w carryon. Upon arrival we were on tarmac for 45 minutes due to no buses for terminal, more than 30 of us missed our connection. Exhausting.
