Angel Flight® pilots own or rent the planes used to fly missions. The planes range from four-to-six-seat single-engine planes to twin-engine pressurized cabin class aircraft. Every plane is subject to annual inspection as required by the FAA. Although these aircraft are comfortable, weight and space are common issues in aviation. For this reason, passengers are asked to provide information about their weight and the weight of carry-on items before a pilot is contacted for the mission.
