on board incidents
good day to you all. i would be grateful if any cabin crew could resolve an argument i am having with a family member. they are flying long haul uk - aus with a change of aircraft enroute in the far east. his doctor has suggested that my dad has oxygen on board just in case he needs it, although it might be only for a very short period if at all. my dad does not want to tell this to the airline because after checking it appears that he will have to pay for the oxygen as it would require an extra seat for which he will be charged for. his view is that he will just be able to use the emergency oxygen carried on the aircraft if he needs it.
can someone clarify if he could do this, or would there be more serious implications if he had to use it.
many thanks in anticipation of your replies. i am only trying to look after my dad.
