The airline will operate new services to Asturias, Belfast, Cornwall, Edinburgh, Klagenfurt and Leipzig – bringing its total routes from the three London airports to 180.
This summer, the carrier will operate more than 3,000 weekly flights to/from Stansted, Gatwick and Luton with 10% growth vs summer 2022.
The growth is underpinned by Ryanair’s $5.7bn investment in the capital, with 57 based aircraft supporting more than 1,600 direct crew and engineering jobs.
Ryanair chief executive Michael O’Leary said: "Ryanair is pleased to bring even more choice to London citizens and visitors for summer 2023.
"Our schedule has grown 10% on last summer, with 3,000 weekly flights scheduled across 180+ routes, including six new sunshine destinations and increased frequencies on 30+ other popular routes like Berlin, Malaga, Mallorca, Nantes and Palma."
