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

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

It was really nice journey i personally recommend klm flight

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

At the airport, terrible, I do not want to even remember it. It was too humiliating for a business class passenger.

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

Over 1 Hr delay. No APU so no AC on ground. Plane was hot during boarding and then they closed the doors over 20 minutes before engine start so interior of plane was steamy hot and stuffy. Could have been helped by opening doors until ready to depart.

First of all we couldn’t check in online, then we learn at the airport we were on stand by for KLM’s mistake of overbooking. The seats were not comfy at all. Our luggage got lost.

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.

The baggage drop-off in Stuttgart is bad: after online check-in you cannot use the automated baggage drop off as indicated on the website. You can use the terminals but have to cue to 1 of three open and slowly working counters to drop the bags. took about 45 minutes wait time.

The map feature on the display at the seat had challenges. The biggest issue was the flight had no WIFI. Most of the smaller planes now have free WIFI. American Airlines on the flight over had WIFI you could purchase. With 8-10 hours on a single flight, the ability to do work via WIFI is essential!!

A shout-out to the flight attendent, Lauren, who was the main person assisting me. She was amazing - perfect balance of bright, cheerful, engaging, yet formal

Cramped seating but standard in all smaller aircrafts today no matter what airlines. Crew very helpful, friendly & attentive so makes up for that.

Wonderful business class flight in a lovely new plane with an excellent crew

OK, except for a cabin attendant's lack of attention.

efficient. on time. cabin crew were very professional and very nice to deal with. would definately fly BA again.

It was great overall. A few slight improvements could be made on the onboarding process at the Gates with announcements and clarity of communications (both at the gate and in flight). The movies in the entertainment options could be improved for bollywood, hollywood.

I alrady responded to this request, and expllaned at length that this was the worst flying experience in my 77 years. I will NEVER fly BA again.

Airbus A350 is poorly designed for wheelchair users and reduced mobility passengers. The angle of the pods makes it awkward to transfer. I was able to but I have ab stability. It could be a real challenge for people with more severe mobility impairments. You'd think Airbus would have come up with a solution for this or thought more about us disabled folks more when designing this aircraft.

The crew has always been great on BA. They are very friendly and accommodating. I like that they have vegetarian options already in the menu. And the free wine is a nice perk.) I noticed (both directions of my trip) minor upgrades/ replacements needed on the plane itself (touch screen didn't work with touch; bathroom light didn't go on). However, this is one of my favorite airlines.
