Complaints about credit card surcharges for air travel are being investigated, according to the Chairman of the Isle of Man Office of Fair Trading (OFT).
Bill Henderson said there was a lot of public concern, even though the airlines serving the island are all compliant with current regulations.
The Isle of Man OFT has informed regulatory body, the Civil Aviation authority, about the complaints.
Mr Henderson said: "We are doing what we can, given our legal remit."
He added: "I personally don't like the extra charges passengers have to suffer and I hope the airlines take on board there is widespread public concern with these issues".
