Ryanair expects to carry 6 per cent more passengers in Edinburgh next summer, increasing the total to 3.5 million a year.
Tickets for the routes go on sale today, with the airline not expecting sales to be affected by Brexit uncertainties.

Mr Jacobs said there had been no sign of a reduction in bookings from after next March, when the UK formally leaves the EU.
The new winter routes which will continue are to Berlin, Derry, Lisbon, Memmingen, Riga, Seville, Sofia, Stockholm and Tallinn.
