Sales from Triton Travel Group products are projected to hit £140 million this year.
This is an increase from a turnover of £35 million in 2006 and £70 million last year.
Meanwhile, agents were paid £15 million in commissions last year on the sale of Triton products.
Triton director Andrew Botterill said the results spelt out the benefits of being part of the group despite the failure to merge the member consortia into one organisation.
He said: “Despite three not becoming one in terms of ownership, the reason for Triton is even stronger than it was two years ago.
“The results that have been delivered are phenomenal with the amount of commission that goes direct into agents’ businesses.”
He added that the commission payments paid by sales of Triton products “more than made up for lost deals with Thomson and First Choice”.
The Triton group was formed to protect independent agents from commission cuts such as Thomson’s decision to slash commission to a base of 7% in 2005.
