Eastern Airways has said its flight to Southampton from Leeds Bradford should be considered as an alternative link to south-west London.
The recommendation comes after bmi announced that it would be withdrawing flights to Heathrow from the Yorkshire airport.
Eastern Airways, which is based in Humberside, operates three flights to Southampton from Leeds Bradford International.
The regional airline’s chief operating officer, Chris Holliday, said that the flight offers Heathrow-bound passengers "an alternative way of travelling to the south-west of London and the M3 corridor".
"Southampton Airport’s rail station provides a quick direct link to major business centres along the M3 corridor," he said.
"Our air services offer Yorkshire travellers a day return option, including those heading for south-west London."
Flights depart from Southampton at 08:35, 16:00 and 19:15 GMT and arrive at Leeds Bradford at 09:45, 17:10 and 20:25.
Eastern Airways was recently rated number one for punctuality at Birmingham and Newcastle airports.
