Cons: Agent changed our flight to Munich and sent as a email with with confirmation on July 10. involuntary. On July 20. I checked Lufthansa app and found that only flight that was shown was flight Toronto-Thunder Bay. After 3 hours of phoning I found that flight from Munich to Toronto wasn’t available for date that was given us in email. Only option was day earlier or later. Left us to take day earlier and we could not changed last flight( Toronto- Thunder Bay). We had to come on Aug 22. and stay in Toronto for 27 hours and than take a flight to Thunder Bay on Aug 23. We lost a day of our vacation, had to stay at hotel. Not good experience at all. We still don’t know whom to complain about that.

Mediocre 2.0

Cons: We waited THREE HOURS just to check our bags; we didn't have time for a meal prior to boarding as a result. Were told in-flight that they should've given us vouchers, and now we'd have to pay for something to eat. Our luggage was lost and took four days to be delivered.

Cons: Boardingvwas delayed so we left a good 50 minute late. Ran out of meal choice so we had to eat what they had left which was pasta that was too spicy for me anyway. I was very disappointed bec I preferred chicken but there were none left.

Prices are per person, are for e–tickets and include all taxes & fees in EUR.

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 hires 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.
