We take a wheelchair for every veteran on every flight, for their use if needed during the trip. If a veteran requires oxygen, their health care provider must supply a prescription that identifies the delivery method (mask or cannula), frequency (as needed or continuously), and the rate of delivery (liters per minute). Greater St. Louis Honor Flight will provide an FAA approved oxygen concentrator for use on the plane as FAA regulations do not allow oxygen cylinders on board. Oxygen cylinders to be used while in D.C. will be provided. However, veterans are responsible for providing oxygen for use from home to Lambert Airport in the morning and from Lambert to home in the evening.
