I think that would b such a selfish thing to do,
The guy is asking well in advance of a flight in an attempt to be prepared, to make the journey as safe as possible for his Dad - this is in no way selfish - check yourself.
with me being crew i would b so angry that this was never brought to our attention that your father needs oxygen just because he cant be bothered to py £150 which could save his life.. I hope hes not on my flight
COPD affects about 5% of the developed worlds population, odds are that you'll have a passenger with COPD on almost every flight. You then have to factor in every other illness that isn't disclosed to the cabin crew - CHF, Angina, emphysema etc... there'll be multiple potentially serious medical conditions on almost every flight. You don't have time to get 'so angry' so many people now do you? Getting angry at someone because they require medical attention probably isn't part of your training either. Calm down, it can't be good for your own blood pressure, then you'll have your own medical condition to announce every time you fly.
I tell u that after you posting a very very selfish thread..
Apologies are really in order for that comment.
We dont get trained AVMED just for fun its real medical emergencies that occur unexpected!!
If this is how you react to a perfectly reasonable query from the public I'd question your ability to react to a real emergency.
