A consultation has begun into the closure of Manston Airport
It comes after airport officials announced the potential closure of the Thanet airport earlier this week.
A Manston Airport spokesman said: "Following a meeting with staff at Manston Airport in Kent today we can confirm we have commenced a process of consultation over the possible orderly closure of the airport.
"No further comment will be made until the consultation period with staff has been concluded."
The news comes as a shock as there was speculation that under its new owner, the airport could have a future.
