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.
