Australian airExpress is a logistics company based in Melbourne, Australia. It operates freight-only services within Australia using leased Qantas, National Jet Systems, and Pel-Air aircraft and a fleet of land vehicles. Its main base is Melbourne Airport.
AaE flight operations are somewhat complex and varied. "Next Flight" services use space on the next available scheduled Qantas passenger flights. Items carried for Overnight, 2 Day Economy and Off-Peak deliveries are flown on both Qantas and Australian airExpress aircraft operated by Express Freighters Australia, National Jet Systems subsidiary National Jet Express, and Pel-Air. The company does not service the Northern Territory 'overnight' from Sydney. Due to the three different service providers, AaE flights operate using different flight numbers and callsigns.
The Express Freighters Australia Boeing 737s use Qantas flight numbers and callsigns as the ground handling is done by Qantas/Express Freighters, while National Jet Express uses the aircraft registration as their callsign and uses the IATA designator XM for its flight numbers (and uses the ICAO designator XME). Pel-Air flights also use XM flight numbers but have no specific callsigns. AaE also has an international Division called Australian airExpress International.
