Having grown our London Stansted traffic from 13.2 million in 2013 to over 20 million this year, this new deal will allow Ryanair to continue to expand our route network at Stansted, our largest European base.
Stansted divisional chief executive Andrew Cowan said: “Today’s announcement by Ryanair is fantastic news for Stansted Airport and passengers from across the east of England and London.
“Ryanair is an important and valued partner for us at Stansted and we’re delighted to support the airline’s exciting expansion plans for the summer, which will help ensure Stansted remains one of the UK’s fastest growing airports and see us serve well over 25 million passengers a year within the next 12 months.
“Stansted sits at the heart of one of the UK’s most innovative and rapidly developing growth corridors between London and Cambridge, so the new destinations and increase in flights on key routes will offer passengers and businesses even more choice at great value.
“This builds on the strength of Ryanair’s extensive network at Stansted that now serves 140 destinations from the airline’s largest base in Europe.”
