Aloha Airlines is unique in that its jet fleet consists entirely of two types of Boeing 737 aircraft, a standard version for the interisland runs and a long-range version with wider wings and bigger fuel capacity for the mainland trips.
Its safety record rates a “A", the highest grade possible, according to Air Rankings Online (see rankings at Airline Rankings). Rankings are cumulatives, based on the number of fatal accidents per million flights that the carrier has flown since 1970.
