The clock that matters is door to door
Flight time is the shortest part of a medical transfer and rarely the part that decides the timeline. What matters is elapsed time from the bedside where the patient is now to the receiving bed, which includes acceptance, aircraft positioning, ground ambulance legs, handovers and, on international movements, border formalities.
We give timings on that basis. A five-hour flight can sit inside a twenty-hour door-to-door movement, and knowing that upfront is more useful than being told the flight is short.
