Additions include three new routes from Aberdeen to Haugesund in Norway, East Midlands airport, and Guernsey (via Newcastle).
From Newcastle, Loganair will fly to Bergen – also in Norway – and operate a seasonal summer service to Guernsey.
It will also launch its first route between Glasgow and Cardiff.
All flights will be operated by Embraer 135 or 145 aircraft and will fly year-round, with the exception of Guernsey.
Loganair will fly the Glasgow-Cardiff route daily, with the other five routes operating six times a week excluding Saturdays.
The additions grow Loganair’s route network to 36 destinations across seven countries.
