Ryanair has opened a training center at London Stansted Airport, as it seeks 1,000 more pilots, cabin crew and engineers this year to fuel its expansion.

The European training center includes four full-flight simulators, an aircraft interior for cabin crew training and a full-scale engineering training aircraft.

“These new facilities will allow Ryanair to recruit and train over 1,000 pilots, cabin crew and engineers in 2016, and many of these jobs will be based across Ryanair’s 13 UK based airports, where we are adding 14 new aircraft, and growing our UK traffic from 36 million passengers to 41 million passengers in 2016,” Ryanair CEO Michael O’Leary said at the May 16 opening.

O’Leary also used the event as a campaign platform, supporting the UK’s continued European Union (EU) membership.

“It is exactly this type of investment that will be lost to other competitor EU members if the UK votes to leave the European Union,” he said. “I am absolutely certain that the UK economy is better off in Europe, and that is why Ryanair is campaigning hard and actively calling on UK voters to vote ‘Remain’ on June 23.”
