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.

On a long flight, it was great having an empty seat between me (window) and the other passenger in my row (aisle), especially given that I paid an extra $55 for my seat.. ( I do need to add, however, that 5-6 hours into the flight, a passenger two rows back became ill which required that the row be vacated so I ended up with a young woman sitting in the middle seat next to me who announced that she was sick -- and looked that way.)

Food was really poor. Other airlines do a much better job! Also, it would have been nice to have had the kind of curved headrest that makes it easier to sleep, especially on a long flight. The short flight from Dublin to Alicante offered this kind of headrest.

We were delayed several hours and were never told why. Mostly there were no Aeroflot staff at the gate to ask. When there was, they said they couldn't help us because our flight was a codeshare with FinnAir. At the last minute they switched gates, sending us all scurrying.

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.

Both flights, outgoing and returning, had the same problem. My family was spread all over the plane. My wife was in the back, I was in the front, and my two kids (ages 2 and 4) were split apart in the middle! Aer Lingus won't allow kids to be checked in online or over the phone so we couldn't address this until we arrived at the airport. At the check in desk, Aer Lingus personnel who are usually very accommodating told us "I'm sorry. It's a full flight. You'll have to talk to the flight crew." As if boarding a an international flight with two toddlers isn't difficult enough, now we had to do it without knowing where are seats were. All I can say is thank God for the accommodating passengers on our flight. The flight attendant was not helpful so I had to ask people myself.

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.
