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.

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.
