After the collapse of airline Flybmi on Saturday, Loganair has taken on five of the routes.
Loganair said it was in a "strong financial position" and would be flying from Aberdeen to Bristol, Oslo and Esbjerg, as well as from Newcastle to Brussels and to Stavanger in Norway.
The company was also "evaluating Flybmi’s wider network."
At the moment, Loganair flies to the Scottish Highlands and Islands as well as to a small number of destinations in England, Ireland and Scandinavia.
Jonathan Hinkles, Loganair managing director said: "It’s always really sad to see an airline go out of business, and our thoughts are with all those affected – particularly staff members.
"We are evaluating Flybmi’s wider network and assessing routes which align with Loganair’s distinct geographical area and overall strategic plans. We are also working on employment opportunities for pilots, cabin crew and engineering support staff to strengthen the Loganair team."
Flybmi has also advised customers to seek refunds from credit and debit card companies or rebook with other airlines.
The company collapsed late on Saturday, with thousands of journeys cancelled.
Passengers stranded across Europe told of their frustration after regional airline collapsed.
The airline, which flew to 25 cities, said uncertainty around Brexit along with rises in fuel and carbon costs led to it filing for administration on Saturday. It means that 376 jobs have been put at risk.
