CommutAir

CommuteAir (IATA: C5), commonly seen by travelers as a United Express operator, is a U.S. regional airline headquartered in the Cleveland metro area, with hubs/bases at Houston Intercontinental (IAH) and Washington Dulles (IAD). Its network is regional: CommuteAir says it connects smaller communities through United’s global network, primarily with Embraer ERJ145 aircraft. For trip planning and crediting, treat these flights as United Express/United itineraries: the relevant alliance context is Star Alliance through United, and the frequent-flyer program is United MileagePlus rather than a separate CommuteAir program.
