It's not much more than any other trip that far. Something like a Cessna 310 goes for 350/hr or $2 per mile and it is 4000 NM via Iceland and Greenland. Add in $2000 for hotels and resturants and another $2000 for the flight there via commercial airline and you'd be lucky to do it for $12000 or so. More if you have to pay the pilot. Figure 15k.
