Pros: The crew was amazing, friendly and on-top of it. the filght was great. I was next too a large, smelly man and that affected my flight, but that was out of the airline crew's control made the flight a bit uncomfortable.
Cons: Not to be seated next to a large man and a child behind me kicking my seat. Again, items out of your control. There is one item, and that is, I forgot to request a vegan food option and it would have been nice to have one last minute even though I did not request it.
Pros: The crew tried to be helpful but were equally frustrated with the ground crew.
Cons: Follow your own policies. Allow people to board (economy plus) with their hand luggage who have followed all the rules and chosen a seat in the front of the plane. My daughter and my KLM approved baggage were taken by the boarding crew while allowing other passengers to go with more than allowed

We’re not the seller
At KAYAK we don’t set prices, so it’s not possible for us to guarantee what other companies are selling.
We aggregate tons 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 don't guarantee prices we find.
Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires 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.
