Unite, Britain's biggest union, have expressed fury at the decision to close Manston Airport despite viable offers being made to buy the airport.
Around 140 jobs will be lost at the Kent airport when it closes on the 15th May.
There have been discussions with potential buyers following the announcement in March that jobs are placed at risk.
Unite regional officer Ian McCoulough said:
We are shocked and very angry. We can’t believe that the owners of Manston have rejected a viable offer to buy the airport which would leave the owners in profit. We believe Manston should continue as a viable airport.
"It is vital to the local economy in terms of employment and economic growth in Kent. "
