Pretty basic one hour flight so there's not much to complain about or praise about. I got some sleep which was good.

The crew had their general Dutch aloofness on form. Chatted to one of the stewardesses in Dutch up until she saw I had a British passport then she decided she could only speak English to me.

787 is a great airplane. The 3-3-3 seat configuration leaves enough seat width to be just comfortable in coach.

The last two times we connected in Amsterdam to Humberside our luggage was delayed. This time it wasn’t. The simple things give the greatest satisfaction

Excellent experience with the cabin crew.

Seats on the 777 were too narrow. This 777 had a 3-4-3 seating arraignment, it would have been better with a 3-3-3, similar to a 787 configuration. With the current layout, even with an aisle seat, I was sitting in the aisle. And I am not a large person! The flight was full, so use the 787 and two daily non-stops. For a twelve hour flight, the food was only Okay, could have been better and with a better selection. Meal timing was poor.

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.

The crew and the plan and the service were all top notch. However, their new policy as of 1/1/2018 in which they even charge for coffee and water seems very misplaced and excessive.

Nice seats, comfortable.

Again, no aisle seat for SkyTeam Gold member. Also, my baggage was lost. First bag arrived a day late, second after I had left Billund and it was six days before the bag with my clothes reached me. I was told I will have 100 euro credit for clothing, but in the winter and for 6 days, this was not even close to the amount I needed for clothing and necessities, to have my time here.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.
