for the second time on this flight, the onboard devise for credit cards would not accept mine. this is the same card i used to book the flight. i complained to british air last time but they obviously haven't fixed the problem. there seems to be a problem using american credit cards these flights. is is a problem because nothing is free. luck;y a flight attendant did feel bad about it and gave me a glass of water

I have to rate British Airways as a 10 out of 10 in almost all categories...comfort of the plane, food and service, boarding, notifications, crew, etc. In particular, the long haul flight from London to Seattle everything was truly top notch!

Their baggage handlers damaged several parts on my checked-in luggage...three zipper pulls and one clasp. What are they doing with the bags? How can they damage so many things in one fell swoop? This is a good quality Atlantic suitcase. Also, on the short flights, in this case Madrid to London, they are now charging for EVERYTHING...even water and coffee. They said it was a new policy as of 1/1/2018.

Cabin crew were friendly, efficient, courteous Refreshments generous and excellent. Good movies.

Rather than boarding economy passengers by row number, there is a free-for-all at the gate, and tedious blockage in the aisles as passengers wait for others to place carry-on luggage. More leg-room than United, but still a bit crowded for tall people. VERY BAD DESIGN of arm-rests, which do not go up all the way into the seat but instead jut out at an angle.

Everything on board costs extra, including basic drinks and snacks, but that's to be expected on cheaper flights. I assumed that the inflight movies cost money as well, although I didn't watch any because I didn't have headphones.

The cabin crew were pretty good. That's about all that was good.

I paid almost $400 for upgraded seats. When I got to the airport-- no seats-- both ways!! i didn't even have regular seat assignments. I had to choose from the last few seats available. The ticket agent, the gate agent and the cabin crew all did nothing to make up for the fact that their system screwed up and stuck me in a cramped coach seat in the back of the plane for 11 hours-- TWICE! Beyond that, KLM must have one of the oldest fleets in the sky. Both ways LAX->AMS->LAX, I was on a 30-35 year old 747 with no wifi, no power and a ten-year-old entertainment system. Never again.

Horrible flight; no complimentary soft drinks are served, not even better. The baggage did not arrive and Iberia does not even deliver the baggage, even though the fault was theirs. You have to go to the airport to recover the baggage. I would NOT RECOMMEND this airline to anyone. The plane was quite old and there are no screens on the seats. One of my worst experiences flying in the last 40 years.

Nothing

Carrier at origin Transcaribbean which kyak booked me on left when it decided to without any notification as to why it was delaying. They made us go through security and sit in the gate until almost an hour after it's original departure time. No announcements. The plane sat on the tarmac in front of us the entire time. Most likely they wanted to only make one flight instead of multiple flights to save themselves. Instead of arriving with 2hrs to make my connection to frankfurt I arrived with less than 30 mins even after I rushed to get to their check in point.
