Even though I paid extra for more room, we were very cramped and the seats were hard. Also, when we checked in they did not post the gate we were to arrive at even though we were half an hour away from boarding. The agent did not know either. Actually, the flight from Porto to Zurich did to have the gate posted, and there were very few agents in the boarding areas who could help us. I would never fly Swiss Air again.

Horrible flight. First delay in boarding of approximately 30 minutes. While in the plane, the flight attendants huddle and we get an announcement that the crew's legal time was exceeded, that they don't have replacement crew and that they will need to cancel the flight. One would think that they would know that their time was to be exceeded BEFORE boarding. Took for ever to deplane. Then we were told that flight would not be cancelled but gave us a departure time of 21.15, which of course was not fulfilled. Arrived in Valencia, luggage took 30 minutes to arrive. Absolutely unacceptable

Swiss is the. Only airline I use when I go to Europe. They are on time and they are fantastic!

horrible.. they cause such a problem and my daughter 14 years old was stranded in san francisco

Not good. We returned on united airlines and the food was horrible.

The cabin was warm and few used the blankets. I should’ve upgraded.

The plan was delayed for takeoff by an hour, but we ended up making the landing on time which was a nice surprise.

The crew was very friendly and nice! Very smooth flight.

The meal was wonderful and strawberry ice cream was a plus.

Each flight we took was late with little or no updates or information.

We couldn’t fly to Chicago on our booked flight. The flight was overbooked.

Small seat space for 13 hours flight, they charged for baggage , very bad quality of food,

I was sitting almost in the back, the seats are very tight and there’s no legroom, it’s uncomfortable for a long distance

Absolute worst airline. Charged us $720 to check 4 bags (2 of which were carry-on). Entertainment systems didnt work. And on a 12 hour flight they served 2 meals and never once came around outside of those 2 meals with a beverage or cup of water. Will never fly them again.

Took forever to board. They made announcements without the loudspeaker and since the waiting room was full of screaming kids, no one could hear what they were saying. The business class sleeper seats were designed for tall skinny people. When partially reclined there was nowhere to rest my feet because they did not reach the footrest. and when fully reclined there wasn't room at my sides for my arms. Definitely one of the worst sleeper seats I have ever had.

About an hour delay but we made it to Chicago. I feel that the smaller connecting flights are the ones that cause the delays on the bigger planes that fly international.

Amazing trip! No delays, no broken or lost luggage, and amazing food.

The food we received during the flight was excellent. The service was very friendly. Definitely the best value for the money when flying across the Atlantic.

I use a wheelchair for mobility. Both in my flight from Houston and back to Houston from Istanbul, the Turkish airline staff asked that I claim my wheelchair at the luggage area. On arrival to Istanbul, parts of the wheelchair were in disarray at that time I raised no objection however upon claiming my wheelchair in Houston parts where outright missing. In both occasions, upon arriving in Houston and arriving in Istanbul, I asked multiple times why am made to pick up my wheelchair in the baggage claim rather than at the jet bridge. Getting the wheelchair at the jet bridge minimizes the probability of loosing parts because they can be hopefully reclaimed on the spot. I was told in Houston that a manager turned down my request to claim the wheelchair at the jet bridge in Houston. This is extremely frustrating because a wheelchair is not a set of clean underwear or a toothbrush- this is the way I move. A Turkish Arline staff took my complaint at the luggage claim area in Houston but as of the writing of this review the only contact I have received from the airline is because I initiated a claim rather than her as she told me she would.

The security at the airport was excellent. The one criticism is the boarding process just before entering the plane. There were only 2 boarding lines and there were no barriers thus leading to a mass rush to enter the plane. I suggest that they board by rows, eight or ten rows at a time to prevent the mass rush to enter the plane. Otherwise, I would highly recommend Turkish Airlines
