I would think unreasonable in the sense that it's almost creating a defacto CL at 5000 SC. Qantas might like it as it gives P1's who've hit their 3600 an incentive to keep earning instead of settling down to earn with the opposition.
A clear cut and stated policy of allowing P1 access in busy periods would be preferable. I'm not sure about others but I like a bit of certainty in my travels. Enough random stuff happens to keep it interesting regardless, so when it comes to lounge access, it'd be nice to know that I'm always going to get a comfortable seat, irrespective of how busy the lounges are. That would be a definite P1 perk.
You must absolutely LOVE the Qantas mantra of "Consistently Inconsistent"(tm) then!
Seriously though I think that's a fair point.
I definitely was thinking though of QF possibly wanting increased incentive to keep punters flying post 3600 mark. Imean the points bonuses? Kind of ho hum really. I reckon most of us who have reached P1 once, or multiple times, would be pretty points rich.. an extra 50k or 100k might be nice sure, but would that be worth extra travels? Probably not if there's a choice in carriers (I mean why keep earning on QF if maybe I can spread my spend to another alliance for example).
The only quibble I might have with the notion of "busy periods" is that while they would be set times (QF definitely defined these periods during the MEL lounges renovations when specific limits were placed on guests andguest passes during defined "busy" times) but by the same token wouldn't the CL potentially have more people in there at those times, as it's likely the peak travel times are likely when these people would want to travel too.
As for CL getting poitentially upset at their peace and quiet being distrubed.. let's say 3 P1 enter a CL during an hour and sit quietly have some food or do work or whatever.. how the heck is that going to disturb anyone else? Further, how would they KNOW that those pax were not also CL unless they asked or knew them personally? That to me is more a lounge management thing.. though I can absolutely see if I was a CL the notion of allowing "extras" in from the Great Unwashed would be unwanted.
I wonder how CL members feel about the policy of (sometimes) allowing P1 into the CL during IRROPS.
Since QF has set a precedent already this is where things become murky. Or, dare i say, "Consistently Inconsistent("(tm)
