I'd say it's very likely most of the fuel-caused diversions affect the longer routes toward Spain and Germany.
Actually, the shortest is KEF-JFK, it's about 2,590 miles, or about the same as U.S. domestic transcon.
In fact, KEF is so close to North America, that FI even flies KEF-DEN on a 752 non-stop (that's about 3,563 mi)
