Hmm, I got the vehicles update, yet at EK- airports in Denmark I can't get Novia as handling..
Novia is correctly assigned to EK* airports but, as explained many times, both on the forum and of course on the GSX manual, the operator are chosen based on a score AND, in case there's a tie, the selection will be random between all candidates with the highest equal score.
Since EK airports are also assigned to Servisair, SAS and Norwegian Air Shuttle, Novia will have to compete with them and, of course, if you park on a parking that has atc_airline_codes for one of the others, they'll get a better score there.
