LOW cost airline Ryanair will launch new summer routes to Berlin and Copenhagen from next summer, but has no plans to add any new destinations to its Prestwick portfolio.

Chief executive Michael O'Leary unveiled the carrier's summer 2016 schedule during a visit to Scotland on Tuesday.

Ryanair will roll out a new four-weekly summer service to Berlin from Glasgow Airport next summer, taking the total number of destinations served to 26.

There will also boost their Glasgow-London services to four per day, with additional flights to Pisa and Riga.

In Edinburgh, Ryanair will launch a new route to Copenhagen along with additional services to Alicante, Barcelona, Brussels, Gdansk, Krakow, London, Malaga, Malta and Palma.

Ryanair's summer schedule from Prestwick, where Ryanair is the only passenger airline, remains unchanged with 16 routes - compared to 24 in summer 2014. However, there will be additional services to Pisa.

It comes after Mr O'Leary promised "very aggressive pricing" on its winter schedule in a bid to pile the pressure rival carriers.

Mr O'Leary said he wanted to take advantage of better than expected profits in the first half of 2015 to cut fares by an average of eight per cent in the six months to March 2016.
