The plane landed much later than expected, and I missed my connecting flight to Moscow. While I was given another boarding pass, I had to have another layover in St. Petersburg, and fly to Moscow from there. The flight turned out to be much longer, and much more exhausting. My overall experience was unpleasant.

No thing at all

1- the aircraft from cairo to munich was so small that they didn’t allow the carry on baggage and I had to put it with the check in baggage. 2- the special meal ( muslim meal ) that I ordered was a veggie meal !!!!! With no meat or chicken at all , apparently they don’t know what the meaning of a muslim meal is ! It means to have halal meat , we are not vegetarians ! 3- my baggage didn’t arrive to the airport and I filed a report and was told that I will have them tomorrow and now after four days the baggage didn’t arrive yet and I was told that one of them is missing !!!!!!! I can’t hate them enough.

12 of January, 2018 Dear Austrian Airlines authority, I address to your kind attention to asist me to get to me the hat qhich I lost on board of the flight 1576 when I arrived to Vienna airport on my way frpom JFK to Lwo. It happened because it was no room above my seat's bin and the steard helped me to get my heat in another bin. Unfortunately I forgot at the moment when I left the board of the plane, a minute later I reminded that I forgot my hat but I was not allowed to go back and get my hat. I tried to communicate with the Lot&Found office in Vienna airport as I had 2h40 minutes in connection time and it was enough time to get me back the hat, unfortunately nothing was really done from the airport staff to get me my hat and made to me possible continue traveling with my hat. I spoke to two managers, the name I could share with you if you need. The Found office registered my black hat and the plastic box under the number F2018/000682. In this situation I ask your offices to deliver my hat and the plastic box to Lviv airport as sson as possible as this is a special hat for my daily prayers. I wish you best and ask for your kind assistance to send the item as soon as possible with the nearest flight. Sincerely, Meylakh Sheykhet

Crew was courteous and polite! Entertainment system had some great movies at no additional cost.

Poor communication between delta, KLM and Air France meant that I couldn’t check in online and get a digital boarding pass. Furthermore I couldn’t use the check-in kiosks because my name was listed as Reidmr instead of Reid, which meant that my boarding pass did not match my passport. Overall this caused unnecessary delays that were compounded by the fact that I couldn’t use my TSA precheck. My main problem on the plane was that I had to struggle to get water served to me. It’s always so dry on planes and I would have liked to be able to get more than one tiny glass of water at a time. Also, would have loved a window at my window seat. Plus no WIFI!?

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.
