Go! says that it had its best day yet of ticket sales on September 22. The carrier, a division of Mesa Air Group, started inter-island service in Hawaii in June. Contributing to the demand that day was a fare sale that Go! instituted, with one-way fares on selected flights starting at $19. That sale, matched by both Hawaiian Airlines and Aloha Airlines, runs through the end of this month for travel on specified flights through Feb. 28, 2007.
