Nothing remarkable

I got up to use the bathroom and I was seated in the 10th row. When I was trying to make my way back to my seat, the beverage service had started. They were at the 12th row and after bumping into me, the flight attendant asked me to back up and wait until the beverage service was over to go back to my seat. This was a flight from Frankfurt to Zurich, only about an hour long, and I would have easily spent half of it standing up had I complied with their request. I had to be pushy and ask them to just back up the cart 2 feet so I could get to my seat, which only took them 5 seconds. This was a very rude, illogical, and unreasonable request from the Swiss Air crew.

Excellent 8.0

Cabin crew were friendly, efficient, courteous Refreshments generous and excellent. Good movies.

Rather than boarding economy passengers by row number, there is a free-for-all at the gate, and tedious blockage in the aisles as passengers wait for others to place carry-on luggage. More leg-room than United, but still a bit crowded for tall people. VERY BAD DESIGN of arm-rests, which do not go up all the way into the seat but instead jut out at an angle.

The flight was on time, the food was good. Nice selection for onboard entertainment. The plane was very clean.

1. The boarding process at Istanbul airport was horrible. No one could speak or understand english. My father was on a wheelchair and he was the last one to be boarded on the plane! There was so much confusion - some people wanted me to go separately from him, others wanted him to walk down the stairs on his own, etc. etc. There were hardly any announcements for people with special needs. Generally they are allowed to board first as they need more time to settle. I could barely find overhead bin space for his stuff. 2. There were several remote controls broken on the plane. A lot of people had to suffer through a non working entertainment screen. 3. One of the hostess was hardly listening to anything I had to say. She seemed to be in so much of a hurry and had a very bad attitude.

Horrible flight; no complimentary soft drinks are served, not even better. The baggage did not arrive and Iberia does not even deliver the baggage, even though the fault was theirs. You have to go to the airport to recover the baggage. I would NOT RECOMMEND this airline to anyone. The plane was quite old and there are no screens on the seats. One of my worst experiences flying in the last 40 years.

I'm very disappointed because i wasn't allowed to travel back to the US from Brussels (Belgium). i was supposed to connect in Toronto but because I'm a foreign student in the US, I wasn't aware that i needed a Canadian Visa to transit in Toronto. so lost my flight and i hard to spend another thousand euros to catch the next flight that will connect in the US territory. I made all the call possible to resolve my flight issue and no one could help me either Brussels airline personnel or the kayak customer service. until today i didnt have not even a email to let me know what happen.

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.

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.
