About Hainan Airlines

Hainan Airlines takes its name from Hainan, the island province in the far south of China, and its headquarters are in the provincial capital, Haikou. Beyond Haikou it has major bases in Beijing and other mainland cities, so many of its international flights actually start from those cities rather than from Hainan itself. It is a full-service airline with Business and Economy cabins and is not a member of a global alliance. The route map covers domestic China along with services to other parts of Asia, Europe and North America.

Agents and developers can look for Hainan Airlines on IATA.co in two ways: the booking portal, or the flights API. Hainan Airlines fares appear in your search results whenever our flight suppliers offer them for your route and dates. Bookings are paid from a prepaid balance that you fund in advance. Every fare comes with its own rules on baggage, changes and refunds, and those rules are displayed before you confirm.

Hainan Airlines airline codes explained

Hainan Airlines uses the two-letter IATA airline code HU and the three-letter ICAO code CHH. The IATA code HU is the one shown on tickets, fare displays and booking screens, while the ICAO code CHH is used in air traffic control and flight planning.

Hainan Airlines is a full-service carrier, based in China, operating mainly from Haikou (HAK). It is not part of a global airline alliance.

Booking Hainan Airlines fares as a travel agent

Travel agents book Hainan Airlines fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live HU 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. Hainan 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 Hainan Airlines (HU) through the flights API

Developers and agencies can run the same Hainan Airlines search from their own site, app or back office through the IATA.co flights API. Filter a search by the carrier code HU and read the fares back as JSON, then book from the same prepaid balance. See the flights API and the API docs for the full reference.
