Firstly . The crew were rude ! They did not even response when were calling them from the seat . The only way to talk to them is to find them at the end of the plane ( where they been chating with each other ) Secondly . 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!

The crew were very polite and looked smart, I didn’t find them very personable at all though. The entertainment system is fantastic and my meal was ok I guess, I requested the low fat meal, probably should’ve just had the normal one.

The seats are not very comfortable, very hard and textured seats that just don’t feel nice at all especially on a long flight. I weight about 11 stone (154 pounds) and even I felt like I was taking up a lot of room in my seat.

The onboard crew were lovely.

Stood at check in for over 30 mins with no staff in sight. Boarding was a disaster. Staff was not prepared nor organized and the crowds were unbearable. Upgraded seats were laughable and not worth an extra $60. Food was mediocre. Entertainment would have been good but GE touchscreens are so old, they were difficult to work.

Boarding process chaotic due to conflicting flow of movement in the aisle. People don't like to step aside to let others pass. Additionally some of carry on luggage was oversized and should have been checked into the cargo hold. When flight landed in Nouakchott an announcement should have been made so that the Dakar passengers allowed the NKC ones to deplane, AND the NKC passengers should have been advised to have their boarding passes out for inspection. This caused a backlog in the jetbridge. AND no announcement regarding local time.

Late into the flight there appeared to be a medical emergency taking place just a few rows ahead of me. No announcement was made; it was as though we were expected to ignore the situation. But with the lights in the cabin turned on, a small crowd gathered, and the passenger being vocal in his distress .. . a brief announcement would have been nice: Situation under control, no need to worry, flight will continue as scheduled. The passenger had a relapse a few hours later - again no acknowledgement from the crew to reassure those of us who could hear his cries of distress.

First class was nice onboard the plane, but too tired to enjoy it since it was a 1am flight.

The counters did not open until 10pm, only 2hrs B4 "the flight closed at 12 midnight), even though they say arrive 180 minutes early. The "SkyPriority" line was the slowest line. At the outset two agents weren't even helping guests. This was a very frustrating experience. Unfortunately, I had to pickup and recheck my bag and ended up waiting outside security for several hours because there was no where to drop the bag after passing immigration from my connecting flight. I suggest AM get another airline's baggage handler to recheck bags for early arriving customers so at least they can wait inside security where amenities abound.

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.
