They provided a pillow and blanket which was very nice, and the crew were helpful in finding space for items during take-off and landing. The boarding and exiting were fairly quick.

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.

I was coming from Sydney and I have to hurry up to take the other fly to Newark and didn’t have time to buy for nothing to eat but I was very surprised they didn’t offer me anything on the plane and when I ask they I have buy it online and didn’t have many choices anyway, I very disappointed with this fly.

Okay 5.3

Plane was about 30% full so plenty of room to stretch out. Friendly crew.

Flight left 50 minutes late because they'd lost the paperwork and had to get new copies.... not very professional! I can understand a delay due to weather or technical issues but losing paperwork shouldn't happen. The food portion was very small for an international flight.

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.

Not only did my other half get our bags for free due to his status with Delta but the amenities they offer and the comfort of the economy seats compared to other airlines is a major difference. As a chronic pain patient, if I can find a Delta flight for a little more, I will be booking with them for sure! Highly recommend them!

Everything went okay for us on this flight. In the future, I will suggest to my wife, who books air travel for us to read the fine print. The cost to check a bag was $100.00 which would have run us $300.00 for the trip: Boston to Brussels with a layover in Reykjavik, but on the return Brussels to Reykjavik with four days in Iceland and the return to Boston, so there goes the cheap flight! I did enjoy the in-flight movie and a documentary on the return trip as well.

My own earphones on the flight from Brussels to Iceland did not work. I could not plug them into the system.

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.

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.

We compile tonnes of data for you
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.
