Pros: We had two seats alone on the side, in row 51(!), with plenty of room and easy access (but not too close) to the loo. The Boeing 747 has aged well and was a bit more comfortable than the 787 Dreamliner we took over to Europe.

Cons: Only downside was the clunky seatback entertainment screen, which probably looked bad 20 years ago when they put it in.

Pros: Helsinki is a convenient connection to fly to the U.S. One of Finnair planes was damaged earlier in Chicago and they used AirItaly to operate this flight. I was traveling with a recent wrist fracture and I was lucky I had an empty seat next to me that allowed me to move my arm a lot to avoid swelling.

Cons: Our boarding was an hour and a half delayed

Mediocre 3.6

Pros: Boarding staff & crew were fine

Cons: The seats were the most uncomfortable I have ever travelled in - this plane definitely has the worst seat width, leg & reclining space that I have seen. I have been in long-range (16 hours) flights that were more comfortable than this. If anything fell on the floor, I couldn't retrieve, I couldn't sleep at all & had contorted joints & a body ache when we landed. To design such tiny seats is truly inhumane.

Pros: The red wine was good. The flight was smooth.

Cons: Unpleasant boarding experience: While my carry-on item was well within the Lufthansa guidelines, the lady in charge of boarding insisted that it was too big and did not allow it in the cabin. I have used the same bag in previous Lufthansa flights without any problem. She sarcastically told me that "I am not Americanaki" - a derogatory expression used by those in Greece who consider the Americans naive.

Okay 5.6

Pros: The issue is not with Lufthansa but with the Berlin Airport. First of all, It is not clear that you have to do the checkinn at terminal B and then come back to the gate where you have to go pass security. This is when it gets even more complicated, the line is long and slow, there is only one security arch and xray machine, is took us almost an hour to go through.

Okay 5.6

Pros: Relatively fast flight

Cons: No entertainment or perks at all. And the worst thing was that before flight, they closed us in an insulated gate especially for flights to Tel Aviv, something made out of the 1980’s with a small kiosk with cold sandwiches and “espresso” from an automatic machine, if we knew this is the case, we at least would’ve bought something to eat before entering the 80’s terminal/gate.

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,
