Pros: That I got to visit a place as mystical as Iceland for such a low and affordable flight. My departure flight with Iceland Air was on time and although the return was a bit tardy the company did an excellent job with being transparent.
Cons: The flight crew could have been a bit more polite

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.
