Hokkaido International AirlinesHD

AIR DO (stylized as AIRDO) is a Japanese regional airline headquartered in Sapporo, Hokkaido. Founded in 1996 as Hokkaido International Airlines, the carrier launched operations in December 1998 with its inaugural flight from Tokyo Haneda to Sapporo New Chitose Airport. The "DO" in the name refers to "Hokkai-DO," reflecting the airline's identity as the "Wings of Hokkaido."

After financial challenges in the early 2000s, AIR DO restructured with support from All Nippon Airways (ANA), establishing a strategic partnership that continues today. The airline operates an all-Boeing fleet of 14 aircraft—nine Boeing 737-700s and five Boeing 767-300s—serving routes exclusively between Hokkaido and mainland Japan. In 2022, AIR DO joined Regional Plus Wings Corporation, a holding company shared with Solaseed Air.

AIR DO offers competitive fares on Hokkaido routes while maintaining full-service amenities including complimentary beverages and in-flight snacks featuring Hokkaido specialties. Through its ANA codeshare partnership, passengers can earn ANA Mileage Club miles on qualifying flights or accumulate DO Miles through AIR DO's own My AIRDO loyalty program.
