Was charged 65 pounds for checking one bag. This was a big news to me. BA claims it was because I booked through Kayak. Would not have booked the flight.

I have always known of airlines to offer preboarding to those military members in uniform or on official orders. Delta took it one step further and allows prior service members to board also.

I've always wanted to go to all five Manhattan boroughs in one day. Thanks to Delta, that happened.

The plane broke down as we were about to take off. Delta rebooked everyone on to new flights because it was pretty obvious that plane was not going to be fixed in time. The crew did their best given the situation. The situation was absolute bs though - we had to take a cab to JFK for our new flight and do the whole security thing again and all that annoying stuff. Thanks for wasting 8 hours of my life, Delta.

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.

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.

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.

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.

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.

If you have more questions or if you have a bad price to report to us,
