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

Pros: Although there were delays they kept us informed on a regular basis as to what to expect and seemed genuinely apologetic for any inconveniences. Boarding and deplaning were smooth and efficient. I really appreciated that there was no charge for checking a bag. I am certain that contributes to the ease of everyone getting on and off the plane. Our bags arrived at baggage claim about the same time we got there. I would definitely fly with Virgin Atlantic 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.

I had a small back pack and a small suitcase. The boarding staff were extremely rude and wouldn’t let me take both on board. Only one small bag on board even though there was tons of space and I paid for premium seat. Also—they want you to wear their mask—even though I had n95. Will definitely avoid this airline in the future

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.

I choose Lufthansa cause it’s a good airline with great quality but this one was soo old and poor. Food was terrible. Blankets and pillows very old, looked like they were like used. The chairs were soo uncomfortable

my flight was cancelled and I was not notified of this. in fact I got a confirmation on September 7, 2021 from Kayak and when I called to check on seats that is when I was told that flight was cancelled back in April. I had to spend the next 3 hours scrambling to change my entire trip and still have not received my entire refund for the cancelled flights.
