I am frankly pretty suprised that no airline has make an effort to compete with FI on flights from the US to KEF. Iceland is one of the fastest growing tourist destinations in the world and I think that maybe at the very least a thrice weekly service from a U.S. city, perhaps a summer only service? Does Iceland make slot access hard to foreign carriers? Think about it...there is NO competition on those routes. The only airlines that I could see possibly giving KEF a shot eventually are DL (maybe a 757 or 738 from JFK or ATL), CO (a 737NG from EWR), and US (a A319 or A320 from PHL). Its just suprising that no one has given it a shot at it.
America's chickens are coming home to rooooost!
