Loganair is to take over two Flybe routes from Edinburgh to Norwich and Cardiff when the airline drops them next year.
Flybe customers already booked on these flights will be automatically re-accommodated on the relevant Loganair service.
The airline will withdraw from the routes at the end of March 2014.
The agreement comes after a five year franchise deal between the two airlines, with Loganair currently flying 25 routes under the Flybe brand including Norwich to Manchester and Guernsey.
Scottish airline, Loganair will start a double daily weekday service between Edinburgh and Norwich in April, adding a third rotation after the Easter holidays.
A Sunday service will also be added, with Sunday frequency increasing to two flights during the peak summer season.
For the Cardiff connection, the airline will be commencing a triple week-day flight and a twice daily rotation each Sunday.
