About Hong Kong Airlines
Hong Kong Airlines is a full-service carrier based at Hong Kong International Airport. It does not belong to any of the three global alliances. Most of its flying is regional: mainland China, Japan, South Korea, Taiwan and Southeast Asia make up the core of the network, and a limited number of longer routes are added from time to time. Cabins are Business and Economy. Do not confuse it with Cathay Pacific or HK Express, which are separate companies that share the same home airport.
If you sell travel to or through Hong Kong, you can check Hong Kong Airlines in the IATA.co booking portal or query it through the flights API. Hong Kong Airlines fares appear in your search results whenever our flight suppliers offer them for your route and dates. Bookings are deducted from your prepaid balance. What is included in a ticket depends on the fare, and the rules are displayed before you confirm.

Booking Hong Kong Airlines fares as a travel agent
Travel agents book Hong Kong Airlines fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live HX fares in the booking portal: the price, baggage and fare rules are shown with each offer before you confirm, and the amount is deducted from your balance. Hong Kong Airlines results appear whenever our flight suppliers return them for your route and dates, so what you can book follows live supplier content rather than a direct airline deal.
Search Hong Kong Airlines (HX) through the flights API
Developers and agencies can run the same Hong Kong Airlines search from their own site, app or back office through the IATA.co flights API.
