Workers at Manston have presented two separate business plans to management that could ensure the viability of the Kent airport.
The Unite union said the workforce had presented short-term and long-term business plans to management that could chart a profitable future for the airport.
Unite has also asked the company to extend a 45-day consultation period – due to end on May 11 – so that all options can be explored to safeguard the future of Manston, which employs 140 people.
The airport was bought by Ann Gloag, who co-founded the Stagecoach Group, for £1 in October last year.
Unite regional officer Ian McCoulough said: “The workforce prepared two impressive business plans in a very short time to save Manston from closure for the management to consider.
“The employees are doing all they can to chart a viable future for the airport which is vital to the local economy.
“Its closure would be a hammer blow for Kent – however, the airport’s future looks a bit brighter this week with the presentation of these two business plans.
“The management have now taken away the plans to consider and we will be meeting them again next Thursday.
“We also want the consultation period extended from May 11 to give more time to investigate every avenue to save the airport – we think that’s a reasonable request.”
Unite is also investigating possible alternative job opportunities for its members at other airports in the southeast of England.
