I wanted to buy an checked-in luggage, but Austrian site did not worked properly, repeatedly gave an error message. I ended up buying it at the counter desk, in the airport, at a much higher price.

Crew was super nice, service great and plane comfort appropriate for the duration of the flight.

Overhead compartments very narrow and could not fit small carryons.

Staff and flight were great. We were surrounded by kind of rude flyers. They complained when my husband moved the seat back. And they were just standing in the aisle most of the time. Person in front of me stretched her arms over the seat so her hands were dangling in front of me and fingers in my screen. I know we were in coach, but maybe another inch of separation would be nice for such long flights.

See above.

The flight was basic service to get me from one place to another. It was completely average and not quite the Austrian service I have previously known.

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,
please send us an and someone from our team will get back to you promptly.
