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!

A little more options in entertainment in the hindi language would be much better for people who do not like to watch English entertainment. Along with that free wifi would be kind of good to have for people who need to work on the flight or check out important emails.

Pretty basic one hour flight so there's not much to complain about or praise about. I got some sleep which was good.

The crew had their general Dutch aloofness on form. Chatted to one of the stewardesses in Dutch up until she saw I had a British passport then she decided she could only speak English to me.

Again, no aisle seat for SkyTeam Gold member. Also, my baggage was lost. First bag arrived a day late, second after I had left Billund and it was six days before the bag with my clothes reached me. I was told I will have 100 euro credit for clothing, but in the winter and for 6 days, this was not even close to the amount I needed for clothing and necessities, to have my time here.

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.

We had to walk from gate z all the way to gate B carrying all the bags which was painful, the plane was very tight and old that I had to put all my carry on bags in the floor. I personally had to help the crew members to pick up the food trays because they were very limited and no entertainment at all which was really boring.

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.
