THE Travel Industry Council (TIC) has promised to help holders of tickets on the grounded Cambodia International Airlines get refunds. The tickets for flights between Hong Kong and Phnom Penh became invalid when the airline cancelled services on Christmas Eve. TIC executive director Peter Siu King-sun said: 'Our travel-agent members will try their best to help the customers to claim reimbursement from Cambodia International Airlines.' He said he did not know how many tickets had been sold by travel agents, but Marvel Tours put the number at 10,000. The Thai-owned airline was closed by the Cambodian Civil Aviation Authority in favour of a national carrier. The Consumer Council yesterday reported the first complaint from a person who had bought an open-dated ticket. Meanwhile, the 68 Hong Kong tourists stranded in Phuket will return today on other flights.
