Passengers will be able to travel between the Channel Islands and Scotland’s capital on Saturdays between May 11 and Sept 14 on a 37-seat Embraer 137 jet.
Loganair managing director Jonathan Hinkles said he was 'delighted' to increase his airline's offering from Guernsey Airport.
'It marks the first phase of our summer schedule, which should be a tremendous boost to the island’s tourist industries.
'Last year we provided a seasonal link to Glasgow, which proved to be extremely popular with passengers travelling in both directions, part of the motivation behind adding Edinburgh to next year’s schedule.'
Guernsey Airport’s Head of Aviation Services Ash Nicholas said: 'Guernsey Airport is delighted with Loganair’s launch of the Guernsey to Edinburgh route for 2019, and also continuing with the Guernsey to Glasgow service. These services now give people in central Scotland direct access to Guernsey, during the spring and summer seasons.'
