Gatwick-based seat-only operator Pure Flights has failed with 300 UK holidaymakers abroad.
An ABTA member, the company offered charter flights from several UK airports to destinations in the eastern Mediterranean, including Turkey and Crete. It sold mainly through travel agents.
The Civil Aviation Authority estimates 1,000 customers have advance bookings and will lose their flights.
However, Pure Flights held an Air Tour Operators’ Licence and passengers will be fully reimbursed under the ATOL consumer-protection scheme administered by the CAA.
Those due to travel should submit a claim to the CAA at www.atol.org.uk. The CAA will handle arrangements to fly those overseas home once they have completed their holiday.
