Lufthansa pilots are some of the best in the industry and the flight was extremely smooth from take off to landing. There were bouts of turbulence but the pilot immediately changed altitudes to steer away from it. Flying on the 748 is a pleasure and it's a shame these great planes will eventually all be phased out in favor of more fuel efficient 787s and their Airbus counterparts.

Having to pay 86€ for a second suitcase that weighed just 15kg. In JFK they didn't charge me but Germans always go by the book. I think for the price of the ticket and lower gasoline costs compared to the height of the recession this is simply outrageous. Next time I'll pay for economy plus. You get a seat that is wider than economy but a little bit less legroom than a business one and the second baggage is included. The meal was nothing special but the friendliness of the flight attendants made up for it.

I bought a ticket for three persons: my wife, my daughtet and me. I am Nigerian, my daughter American, and my wife's Turkish. However, because of the diplomatic row between Turkey and the U.S., my daughter was refused entry into Turkey. Turkish airlines' policy was to refund the ticket of any American caught in this row. They said they will refund my one month old daughter's ticket. However, my wife and i will not receive a refund. We bought the three tickets together. Our ticket numbers ended in 235...51, 235...52, and 235...53. However, they will not refund our whole money by cancelling the ticket but only that of my daughter. So this is the question: Does Turkish airline want me to leave my one-month old baby in the U.S. and tavel with my wife to Turkey? What kind of parents will we be if we were to abandon our daughter to take a trip to Turkey. Even, the people in Turkish airlines will judge us evil parents, yet that was exactly the only option they gave us. Lose your daughter or lose your ticket money. They will not even just change our iternary or give us another destination we suggested without penalties which are almost 3/4 of our initial ticket price. They just made away with our money. You cannot say, 'We are cancelling tickets for American citizens' but make no exception for parents of infant citizens. This is the height of criminality. So, me and my family couldn't take the flight and lost $1500. We had to buy another ticket by airfloat to get to Georgia. But Turkish airlines refused to even contact us on the refund for my daughter. A truly criminal enterprise.

They had a vague refund policy for Americans, forgetting that American infants can also have none-American parents who are as much victims in this as the American infant. For them to be myopic and keep repeating talking points of their refund policy is unfortunate to say the least.

Crew was good. Very polite. The plane was old. No place to charge your phone. The in flight screen required the use of a remote which was inconvenient when having to wake up my neighbor to pull it out of the armrest. Food wasn’t great. Skipped the last meal service. It was like flying 20 years ago. Not bad, but not as good as it could be nowadays.

Flight is conformable.. Crew was fine.

experience at the Zurich airport was not good. They checked our passports 3 times before we got to our gate. Swiss airlines should account for these things when they give options for the connections. we had about and hour and half layover and did not even have time to have coffee or anything before a 9+ hour flight. We just ran from one flight to another and barely made to our flight..

Boarding time was supposed to be 19:10, we did not start to board until passed 20:00. Needless to say we were delayed. There was a woman at the counter,but there was no explanation given about the delay. Luckily it was the last leg of my journey and did not miss a connection flight,but being on an 11 hours flight just before, I was a little cranky. Overall I had a great experience.

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.

If you have more questions or if you have a bad price to report to us,
