Brighton-based South America specialist Advance360 Group has ceased trading.
The Civil Aviation Authority (CAA) posted the failure on its website on Monday and stated that some of the flights in Advance360 Group’s flight-inclusive packages are still valid.
The firm also has the trading names Advance Worldwide, Due South, Due West, Go360, Hero360 and See360.
Advance360 Group was founded in 2003 by Brian Penfold.
It is described as “an ethical and responsible travel company” and is independently owned and operated.
On its website the firm describes itself as working with clients worldwide on small group or individually designed holidays.
Advice for those affected can be found on the CAA website.
No one at Advance360 Group was available to comment when Travel Weekly called last night.
