Airports are facing a fight to survive after passenger numbers fell in lockdown.
Regional and smaller hubs are most at risk with some losing more than 80% of customers.
Cornwall’s Newquay airport is one of several that has reported having zero passengers since November, research has revealed.
London City saw the biggest fall in fliers, down from 5.2million in 2019 to 908,105 last year.
Leeds Bradford went from 3.9 million passengers to 751,048 and East Midlands saw its figures drop from 4.6 million to 900,832.
A senior airport source said regionals would find it particularly hard to survive as airlines focus on bigger hubs.

The insider added: “With some local authority-owned, there might come a moment when they can’t justify spending more to keep them open.”
Gatwick saw its passenger numbers fall by more than 78%, going from 46.5 million to 10.1 million.
Heathrow’s plunged by 72%, from 80.8 million to 22 million.
The figures were revealed by luggage shipping website, mybaggage.com.
Boss Paul Stewart said: “Each of these airports is a hub employing thousands.
"There will have been a dramatic knock-on effect across many industries.”
Airport bosses have called on the Government to extend business rates relief until next year and suspend air passenger duty for 12 months.
Karen Dee, of the Airport Operators Association, said the losses suffered by airports were “unsustainable”.
She added: “There will be airports in real difficulties if there isn’t a successful summer.
"It is vital airports get support from Government to see them through the tough months ahead.”
The Government said it has provided “a comprehensive package of measures including extending the furlough scheme, business rates relief and tax deferrals”.
