Ryanair will this winter launch three new Scotland routes — between Edinburgh and London, Glasgow and London, and Glasgow and Dublin.
From October 26, the budget airline will fly three times daily from both Edinburgh to Stansted and from Glasgow International to Stansted.
It will also switch the existing daily Dublin service from Glasgow Prestwick to Glasgow International and add another two frequencies, making it a thrice daily operation.
The new routes are part of Ryanair's strategy of targetting business travellers, including a new corporate fare due to be launched later this summer (see news, July 2).
Despite moving the Dublin route away from Prestwick, Ryanair said it "remains committed" to its base at the airport and is in discussions with the Scottish government, which owns Prestwick, about potential expansion.
Ryanair's decision to base one aircraft at Glasgow International allows it to add a total of seven routes — as well as Stansted and Dublin, it will from October fly to Bydgoszcz, Warsaw Modlin and Wroclaw in Poland, and Derry and Riga in Latvia.
David O'Brien, Ryanair's chief commercial officer, made a plea for APD to be scrapped to allow Scotland to "fulfil its true tourism potential".
He said: "We would urge Scotland to follow the example of Ireland, where Ryanair has launched 21 new routes and will deliver over 1.2 million new customers this year, in response to the Irish government's welcome decision to scrap APD.
"Regardless of the outcome of the [independence] referendum, Scotland cannot unlock its full potential until APD is repealed."
