Okay 4.6

- the staff member who was boarding patients at Glasgow airport (although not on the flight itself) was very rude and impatient. she seemed to be having a bad day - the light was delayed by approximately 45 mins

We missed this flight, so there was really nothing to like. However, the lady at the Swiss help desk was extremely kind and helpful in finding us an alternate flight.

When I booked the itinerary clearly stated that this would be a Swiss Air flight. We were confused when they did not give us our boarding passing for our connecting flight at our original departure desk, and were told we would receive the boarding passes at the gate in Zurich. I never received any notice about his being a Eurowings flight or instructions to check in online. Our incoming flight to Zurich was delayed at least a half hour and it took us a while to get to the gate for our connecting flight. When we arrived, the gate had just been closed and we were told we were not even on the ledger. We were told we would have needed to get our boarding passes at the Swiss Sor desk and required prior check in to be on the passenger list. We were also very confused about the fact that this was a eurowings fight even though our booking indicated Swiss. This has never happened to us before. We would have needed additional instructions for prior check in, and had we been on the passenger list perhaps the plane would have waited for us.

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.
