From looking at the schedules for early April,
Aalborg appears to have gained an additional weekly flight, rising to 3 weekly. The extra flight is on Thursdays and the route now appears to be operated by a Gatwick based plane.
Trondheim appears to have gained an additional 2 weekly flights, taking it to 5 weekly. The times have changed, however still looks like the plane is based in Trondheim.
Will have another gander at the schedules tomorrow to see what other changes have been added.
