Flight attendant for first class is definitely not a morning person. Oh and the WiFi DID NOT WORK!
Reviews
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.
Reviews
Business class crew was extremely helpful and pleasant. Breakfast likewise - tasty, healthy and substantial. All in all, the flight itself was great, so kudos to Finnair. What a contrast, then, to the pitiable Terminal 8 at JFK, where it was almost impossible to even find a seat (no exaggeration!) before security.

Flight attendants couldn’t have been nicer

Delayed and heavy.
Reviews
I liked the perks of boarding first being star alliance gold, but as for the food , wanted more snacks and what they had to offer was not sufficient. Seats were not comfortable as could Not recline and it was not wide enough

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.
