However, a backer has been found "which allows the brand to restart".
The brand entered administration on 8 December.
A CAA spokesperson said Alpine Elements had "approximately 1,000" Atol-protected bookings at the time of its failure. He said: “This is a particularly sad day for customers and employees of Alpine Elements and we appreciate that those with bookings will be deeply concerned.
“However, the Atol scheme exists for exactly this kind of situation and we are making arrangements so that all Atol-protected customers can make a claim, whether they are due to travel or accepted refund credit notes for cancelled bookings.”
