Managing director Rob Kenton thanked loyal customers and his dedicated team in helping the agency, which runs five stores across Berkshire and Oxfordshire, reach the impressive milestone.
He said: "We have worked hard as a family for the past 20 years to achieve this goal and get [to] where we are, it’s a massive achievement for the team.
"It started with a pen and paper in a small village outside Reading [Mortimer] with no customers, and our first booking was a cottage in Devon for around £800."
In its first year the business turned over around £750,000, but this year it recorded £11 million in post-pandemic turnover.
"This year has been challenging for everybody, we were dealing with a situation where we didn’t know what was going to be around the corner," Kenton added.
"Every day something else came along, which made us re-evaluate and start all over again."
Triangle was established on 1 June 2001 and has branches in Mortimer, Pangbourne, Newbury, Wallingford and Didcot.
It acquired its latest shop after taking over John Allan Travel in 2019 following owner John Allan’s retirement after 50 years in business.
The agency has been a mainstay in the TTG Top 50 Travel Agencies for a number of years – with Triangle’s Pangbourne store named Top Agency in the South East in 2018.
Despite only a selected number of destinations being added to UK green list, Kenton backed the government’s "slow and steady" approach to the easing of lockdown restrictions.
"I agree with what the government has done with the green list and I’m confident we will be in a decent position by August/September time," he said.
"For an independent with bricks and mortar shops, the future is bright. I think these are the last couple of months [of restrictions] and we’re in the home straight.
"We have a really good customer base who have supported us from the start when we were just a small agency, but my team are unbelievable.
"They’ve been so committed to it, and no more so during these past 14 months.
"The team has worked non-stop throughout all of it, the dedication, the drive, is just something you cant put a value on.
"Unfortunately there have been casualties but I think my team is the biggest part of the business and without them, you don’t have a business."
