I've mentioned this before, so apologies to those who have read it before

.
Air Canada have a top status category "100K Super Elite" (equivalent to P1) - I think 35K or 50K in their system gets you Star Gold; 75K is about Platinum on the QFF scale. I was only 100K for one year but my experiences of the 'Concierge' service available to 100KSE were outstanding. Although the old hands say its nothing like it used to be.
* One or two Concierge staff at each major Canadian airport and at about 8 major international airports on their network. You could pop in and say hi to them - very accessible.
* The Concierges kept track of every 100KSE passing through 'their' airport, and nearby ports they 'covered';
* The really did act pro-actively in case of delays or planes going tech - hugely valuable if you consider the interruptions due to winter weather in Nth America;
* Often you would be re-booked before you knew there was a problem with your next flight;
* They could and did do other tasks if you asked them nicely - such as making hotel reservations or arrange a limo (they had their own phone numbers, so you could easily phone or text them directly), pick up something from lost property, check if something left behind at security etc.
SE100Ks also got perks such as first dibs at upgrades (could request earlier), better seating availability etc etc. as you would expect.
I've never aspired to get to P1 on QFF, but I did try hard to get to SE100K (and also tried hard last year, but only made it to 75K

). Not sure how the Concierge thing is going these days, but it was great for me while it lasted!
If QFF had something like Concierge, I'd be at P1 in a flash!
