EasyJet is to step into the Edinburgh to Dalaman route in summer 2012 following the collapse of Holidays4u earlier this year.
The low cost carrier is also launching flights to Naples from the Scottish capital next April in addition to Tenerife and Grenoble later this year.
The additional services, which bring the total number of routes from Scotland to 45, will be served by the arrival of a fifth aircraft at Edinburgh airport.
The new A320 is the 200th Airbus in the carrier’s fleet – a milestone that has been marked with a distinctive all orange livery.
The expansion is the latest in a series of Scottish routes announced over the past 12 months including Edinburgh to Basel and Paphos, Glasgow to Jersey and Amsterdam and Aberdeen to Gatwick.
The announcement came as the airline’s first flight to Athens from Edinburgh took off.
The airline’s Scottish commercial manager High Aitken said: “2011 has been an incredible year for easyJet in Scotland, the highlight of which is today’s launch of Scotland’s only direct route to Athens, connecting Edinburgh – the Athens of the North – to the Greek capital.
“Naples will be yet another Scottish first for “asyJet and is set to become a popular inbound and outbound destination. We are also pleased to be able to provide much needed capacity on the popular Edinburgh to Dalaman route.
“This announcement brings the number of new routes which we launched from Scotland in the last 12 months to 8, alongside increased capacity on our popular business links between Glasgow and London.”
