The route comes and goes, it's been that way for several years. In the 90's SAS even had a lounge at the airport.
SFJ is the airport code of the airport (as mentioned), the Danish name of the airport/town is Sondre Stromfjord btw, which might better explain the airport code.
The second international airport of Greenland is Narssarssuaq (UAK).
