Hillgate Travel is urging its clients to support the campaign to persuade the government to cut the levels of Air Passenger Duty.
The TMC said it supported the Fair Tax on Flying alliance of travel companies and organisations in its bid to convince the Treasury that APD was too high and was hurting UK businesses.
The alliance is currently running an online petition for businesses to sign up and register their concern about APD rates – currently more than 400 companies across the UK have added their support to the campaign.
Hillgate plans to help boost this number by promoting the campaign in its customer newsletter, which is distributed to more than 12,000 clients.
Anthony Rissbrook (pictured), Hillgate’s managing director, said: “It’s crucial that policy-makers look hard at the detrimental impact of APD on the UK economy. APD is a hugely damaging tax, making the UK less competitive than our European neighbours and hurting our connectivity with developed and emerging markets.
"I would encourage all local businesses that are concerned about APD to back a Fair Tax on Flying's campaign so that we can demonstrate to the Treasury just how much bewilderment there is about its decision to introduce year-on-year increases in the tax.”
The government has so far rejected pleas from the travel industry about the high levels of APD and has dismissed calls for an independent study to be carried out to look at the economic impact of the aviation tax.
