The Aviation Foundation is a non-profit organisation which has been set up by airlines British Airways and Virgin Atlantic together with airport operators BAA and the Manchester Airports Group (MAG).
Its Great British Flying Test campaign aims to raise awareness of the number of jobs that are dependent on the aviation sector - which employs 220,000 people in the UK directly.
As part of that, the Aviation Foundation argues businesses across Scotland and the rest of the UK "desperately need world-class air links".
Willie Walsh, chief executive officer of International Airlines Group, which owns British Airways, Colin Matthews of Heathrow Airport Holdings, the owner of Glasgow and Aberdeen airports, Charlie Cornish of MAG and Steve Ridgeway of Virgin Atlantic spoke out on the issue.
The four men issued a statement which said: "Local businesses across Scotland and the UK desperately need world-class air links. Britain has been a proud pioneer in aviation but we are in danger of taking this for granted and falling behind our better-connected competitors."
