In 2006, Mesa formed go! in the Hawaiian Islands, using five Bombardier CRJ aircraft from its Honolulu hub. It established a code share with Mokulele Airlines, which served airports that cannot accept jet aircraft and provide point-to-point service in between the islands with Cessna Caravan turboprops. The codeshare with Mokulele was later replaced by one with Island Air, which was itself later replaced by a joint venture with Mokulele dubbed go! Mokulele. The airline ceased operations in Hawaii on April 1, 2014.
