Airlines on this route

Five carriers fly BKK-HKG: Thai Airways, Cathay Pacific and Hong Kong Airlines on the full-service side, with Thai AirAsia and Thai Vietjet covering the low-cost end. Cathay Pacific runs Hong Kong as its hub, the natural pick for connecting onward. The full-service carriers include baggage; the low-cost carriers price the seat low and charge extras separately. Compare the all-in cost once baggage is added before choosing.

THB fares

BKK-HKG fares stay competitive thanks to the frequency, lifting around Lunar New Year, the year-end holidays and the Thai school breaks. For those peaks, six to ten weeks of lead time is sensible. Outside them, the low-cost carriers’ early fares are the cheapest seats, and three to six weeks usually finds a good THB price. Mid-week flights tend to be softer than weekends.

About Hong Kong

Hong Kong is a dense, vertical city on the southern coast of China, built around one of the world’s great harbours. It pairs a major financial district with steep green hills, outlying islands and a famous street-food and dining culture. For travellers from Bangkok it works as a short, intense city break, a business destination, and a connecting point — Hong Kong International Airport’s onward network reaches across East Asia and beyond. The cooler, drier autumn months are the most comfortable to visit.
