All Leisure customers hit by the company’s collapse are being offered discounted holidays by Cosmos Tours.
Those who were due to travel with either All Leisure’s Swan Hellenic or Voyages of Discovery will get £50 per person off a cruise, tour or beach holiday.
Bookings can be secured with a £50 per person deposit.
The discounts apply to the group’s three brands, Cosmos Tours & Cruises, Avalon Waterways and Archers Holidays.
Cosmos Tours CEO Giles Hawke said: "To lose your carefully planned holiday at the beginning of the year is a real disappointment for those looking forward to the relaxation of an ocean cruise."
He added: "As availability on cruises disappears fast at this time of year with all holiday companies running January sales, we wanted to help disappointed cruise passengers re-book as soon as possible."
