Holidaymakers should act fast if they are keen to book outbound trips this Christmas.
Some group tours are already full because of the bullish local economy.
Long-haul trips to northern Europe, Egypt and Dubai have been fully booked since the middle of last month.
And travel agents are reporting a significant growth in the long-haul market as Hong Kong recovers from the financial crisis.
Popular tours include Wing On Travel's 11-day trip to Finland, even though the cost is HK$33,000 per person. The same trip cost HK$26,000 last year, meaning the cost has risen by 26 per cent.
Jo Jo Chan, the agency's general manager, said prices had risen by 3 to 10 per cent year on year on average, mainly because of the weak US dollar and fewer seats on flights.
