You seem determined not to consider the particular circumstances I was describing, which include "And an auntie who lost her husband, who used to organise everything and now she's a bit lost in the airport process" and "someone who is a bit frail or likes company but otherwise can fly by themselves".
But for the benefit of others, I'll say it again - yes, an airline can look after 'disabled' pax (and I'm describing circumstances where the pax may not be viewed as 'disabled' by the airline), but it can be a matter of whether the flying pax would prefer that assistance by someone they know - even if its a matter of re-assurance and peace of mind.
That can still happen at the airport, but the thread is about lounge access by non-flyers. Right now, if the flying pax has QP access, the helper can too. That's going to be stopped, because, you know, the Spirit of Australia wants things "simpler", so the flying pax would probably self exclude. Again - yay! Less crowding!
And as for it being 'my choice' - geez, I would hope anyone with a shred of empathy and compassion would make the same choice, in the circumstances.
