Island Air (officially Hawaii Island Air) was an independent Hawaiian commuter airline based in Honolulu, Hawaii.^[1] It operated scheduled inter-island passenger services in Hawaii. Its main base was the Daniel K. Inouye International Airport^[2] on Oahu.

The airline maintained a code share and frequent flyer agreement with United Airlines. Hawaiian Airlines halted its commercial relationship with Island Air in 2012 when it announced plans to begin operating ATR-42 regional turboprop airliners in the islands under its own brand. Island Air also operated its own frequent flyer program, Island Miles (formerly Cloud 9).

Island Air ceased all operations on 10 November 2017 after 37 years of service between Hawaii's islands, carrying 13% of intra-Hawaii seats in the first three quarters of 2017, competing against Hawaiian Airlines carrying 80%. For the second quarter of 2017, Island Air posted an operating loss of $4.9 million and a net loss of $8.2 million, and filed for Chapter 11 bankruptcy protection on 17 October as it couldn't find new investors to satisfy lessors Wells Fargo Bank Northwest and Elix 8 who want to repossess its five Bombardier Q400s, which replaced five ATRs.^[3]
