Question

Which rules are applied If a passenger wants to get off from LHO (live human organ) carrying aircraft, during taxi?

Is the passenger get off from aircraft? Or Is priority given to LHO?

Is there an international written rule stating which of the priorities? (ICAO ANNEX, EASA EU OPS, IATA DGR, etc.) Thank you in advance.

Answer 1

Once the doors are closed, the flight is completely under the control and discretion of the Captain.

If she decides not to go back to the gate, the plane does not go back to the gate, no matter what some uppity passenger claims their "rights" are.
