Don't choose KAYAK. They put you into a difficult position which is next to impossible to solve.
The food selection has been better in the past but due to Covid it is understandable. This particular flight did not have any entertainment and the Air Canada App did not work to access movies.
My luggage got delayed, trying to reach out the airline and no updates for me where my luggage is and when it will be delivered to me.
Awesome! I traveled in business, love it!
Crew members were very helpful, friendly and dedicated. The flight was punctual and inside very clean.
Flight attendants couldn’t have been nicer
Flight attendant for first class is definitely not a morning person. Oh and the WiFi DID NOT WORK!
Delayed and heavy.
Great flight Will go again!
Good Morning - we were unable to take the flight from Dublin to Reykjavik because it was delayed and we couldn't risk missing out connection to Denver. At the beginning of our trip the flight from Reyykjavik to Dublin was canceled without telling us and we had to get a different airline on that leg as well. . . When we called the airline, they were closed and unable to help. When we called Kayak, i couldn't understand the person and they were unable to help as well! We purchased the insurance for the trip and sure hope that we can get some help from Iceland Air and from Kayak.
