Ferry flying or a positioning flight is the flying of aircraft for the purpose of returning the aircraft to base, delivering it to a customer, moving it from one base of operations to another, or moving it to or from a maintenance facility for maintenance, repair, and operations.[1]
A commercial airliner may need to be moved from one airport to another to satisfy the next day's timetable or facilitate routine maintenance. This is commonly known as a positioning flight or repositioning flight, and may carry revenue freight or passengers as local aviation regulations and airline policies allow.[2] Such flights may be necessary following a major weather event or other similar disruption which causes multiple cancellations across an airline's network resulting in many aircraft and crew being out of position for normal operations; the 2010 eruptions of Eyjafjallajökull or the mass evacuation of US airspace following the 9/11 attacks being significant examples of this.
