About Alaska Airlines
Alaska Airlines grew up on the US West Coast and still has its centre of gravity there. Seattle is the main hub, with other large bases in Portland, San Francisco, Los Angeles, San Diego and Anchorage, and regional flying handled by Horizon Air and partner operators. The airline belongs to oneworld and sits alongside Hawaiian Airlines within Alaska Air Group. Routes cover the western United States, transcontinental markets, the state of Alaska, Hawaii, Canada, Mexico and Central America, and the group has begun long-haul services from Seattle to Asia and Europe. Cabins are first class, premium class and main cabin.
Booking through IATA.co works the same way as for any other carrier. You search live fares in the portal or over the flights API, choose a result, and settle it from your prepaid balance. Alaska Airlines fares appear in your search results whenever our flight suppliers offer them for your route and dates. Since Hawaiian Airlines flights now carry the AS code too, some results marked AS may be operated under the Hawaiian brand.

Booking Alaska Airlines fares as a travel agent
Travel agents book Alaska Airlines fares on IATA.co without their own IATA accreditation. Activate an agency account, top up a prepaid balance, then search live AS 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. Alaska 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 Alaska Airlines (AS) through the flights API
Developers and agencies can run the same Alaska Airlines search from their own site, app or back office through the IATA.co flights API. Filter a search by the carrier code AS 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.
