No alcohol beverage service before take off. One of the only airlines that does this. Also flight was delayed again in Istanbul. We were delayed on our layover in, and out of Istanbul. Both times stuck on the tarmac. I see this as a common problem

austrian and lufthansa have the worst seats in the industry. good for seating for about 30 minutes ONLY. so tough that make the trip feel even longer. a charger is needed in economy (at least one every two seats). wifi has not made it to this long haul flight yet.

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.

Generally like Lufthansa service - have been flying the airline for 15 years+ Pilots are always excellent

Every flight (to and from India) seems to have the chicken option run out. Why not order accordingly? Had a bad seating experience. LH.com showed that I had completed the boarding process. But when I went to the counter, my seat was changed without my consent (to a worse seat), and I was told that the online process wasn't complete!! Then the website should say accordingly. It's really annoying when this happens. I think the ground crew in New Delhi duped me. At one point, my call button for my meal was ignored for ~30 minutes on the plane. And then I was told there was no more chicken, and handed a veggie wrap. One wonders whether I could have gotten chicken 30 minutes ago!

Firstly . The crew were rude ! They did not even response when were calling them from the seat .

The amount of snacks was limited where’s in Turkish airlines it’s unlimited and you can choose different sandwiches whereas in Austrian airilines can offer biscuits and Cookies ;( Thirdly . We are living in 21 century and most transatlantic airlines have WiFi ! Where’s Austrian did not have it!

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.
