Awful. Delayed for unknown reason. Boarded late, part of a Tight connection ands had to go through customs and immigration. And they lost my bags.

Everything was wonderful! AirBus seats are more comfortable to sleep in as compared to the Boeing planes.

Great. It was awesome to have boarding from the front and back of the plane as it made the process go very quickly

Crew very lovely. Arrived an hour late due to bad weather. We were given new tickets to an other flight but it could have been organised better, so we did not have to run through the whole airport to.

Flight was delayed, short time connection to next flight but we make it, service was good, worth to fly just to try thair on board blueberry juce. Eccelent communication with airline.

It was a pleasure definitely going with Iberia on my future travels

Our connecting flight was cancelled and it took us 15 hours to reach our destination.

Not great. Flight attendants were aloof, food was mediocre, seats that I paid $150 were given to someone else without any concession. I will probably never use kayak again. Terrible experience from start to finish.

Even though we had an airline approved car seat they insisted it was too large to fit in the plane. This same car seat has traveled to 18 different countries on at least 12 different airlines, including our initial flight on the smaller of the two aircraft used for our round trip travel. When we attempted to push the issue we were told to either check the seat or we could just stay in Helsinki (our layover location). The reasoning was because the flight was full, even though we occupied all 3 seats on our side of the plane/row. The the flight attendant then had the nerve to come back and make a smart comment about how the 2 year old was just as safe sitting in his seat alone (complete BS, because anyone who has ever tried to get a 2 yr old to sit still without a seat for 2+ hrs knows it is not going to happen).

The staff were helpful and polite, seat was comfortable, plan was clean.
