I’m not completely familiar with what type of planes are used for medical evacuations, and certainly I understand that if a person is having a medical emergency, they do need to have a trained medical professional accompany them on that medevac if required.

My question is: Does the medical practitioner at the originating end of the medevac have the discretionary ability, if there’s room over and above medical staff on that charter, to allow a family member to accompany the patient on that charter?
