Quite frequently there are air evac operations which are available for hire in the US and internationally. As they are in need of IV solutions and infusion sets , and/or a well trained medical technician and flight staff , med flight establishments have to be coordinated with. Family members require a emergency medical technician — and accordingly they are unable to go on the the big commercial airline establishments. There occasionally are outpatients who utlilize private air ambulance outfits because of the fact that they are in need of being transported and/or are non US citizens. Jet ambulance services are looked up by the family of the patient with a hospital volunteer.
