Up to 2,000 direct jobs hang in the balance after the collapse of Flybe.
The tragic developments threaten a further 1,400 jobs in the supply chain, GMB analysis reveals.
GMB members working for Swissport provide ground services for Flybe at Liverpool, East Midlands, Edinburgh and Jersey airports.
The union warned the airline's collapse put the future of regional airports at risk.
Nadine Houghton, GMB National Officer, said:
"These unfolding developments are a tragedy not only for Flybe's loyal workforce, but a domino effect now puts 1,400 jobs in the wider supply chain at immediate risk and threatens the future of vital regional airports."
"The last thing regions crying out for investment need is to see infrastructure that maintains good jobs ripped away."
"We need the Government to urgently step in and save jobs wherever possible. The damage to already fragile local economies must be minimised."
