The GTMC has tendered its submission to the Airports Commission, following a call for responses on domestic air connectivity between London and the UK regions.
In June the Howard Davies led Commission sought viewpoints from both the public and private sector examining the need for additional UK airport capacity.
It claims the UK economy is missing out on air travel investment from the north of England as growing numbers of business travellers choose foreign hubs over Heathrow due to poor connectivity.
The organisation, which represents major UK-based TMCs, is sharing its survey data with government and policy decision makers with the objective of encouraging expansion at key UK international airports to improve capacity and ensure the UK maintains its position as a “leading country to do business”.
The Airports Commission will publish its findings in summer 2015.
