Menzies Aviation said it struggled to get a place at meetings with ministers during Covid, with the focus on airlines and airports instead.
John Geddes, Menzies’ head of corporate affairs, said: “Everyone talked about airlines, airports and aviation services, but nobody talked to us. We had the devil’s own job trying to get on a government committee.
“We told (transport secretary) Grant Shapps in the one audience we had we would lose 45% of our workforce in six months. Brexit made the issue worse.”
