You designate yourself more or less whilst meeting the usual criteria etc. SNN make a nice few Euro out of the OMNI flights, freight carriers, private, Transaero and others for maintenance/ overhaul etc and until recently was the the first choice of landing for the space shuttle in Europe if there was a hiccup. Not saying that ORK should not operate 24/7 but where is the justification to remain open? Same could be said for SNN perhaps but SNN does generate income in the 12- 6am period .
