The pub, The Windmill, will replace the Wetherspoon pub of the same name, which has been at the airport since May 2003.
The company has spent £2.7m developing the outlet, located airside - 50 metres from the old pub. It is Wetherspoon’s biggest airport outlet and the only pub at Stansted Airport.
The Windmill, which will continue to be managed by Michael Wilkins, is double the size of the former site, offering more than 7,000sq ft of customer space on a ground-floor and mezzanine level.
Runway views
The pub opens from the first flight until the last flight, with cleaning and restocking taking place during closed hours. It has flight-information boards on display, a recharging area for mobile phones and laptops, dining booths and a see-through cellar.
There is a large windmill at the heart of the pub and a bar on each of the two levels, with the all-glass mezzanine level offering views of the runway.
Wilkins said: “The new-look pub is a fantastic outlet and part of the multimillion-pound refurbishment of the airport. We look forward to welcoming new and familiar faces and expect to serve more than one million travellers a year.”
