I'm just about to reach the end of my first year as P1. Prior to this last membership year I used to maintain WP with both Qantas and Virgin, but after a particularly cough experience with Virgin on a work trip I switched everything to QF for the rest of the year and made it to P1.
I'll finish this first year having re-qualified for 2027 with just over 4,100 SCs, mainly from QF F, some domestic J and an unfortunate number of Dash-8 flights.
In terms of P1 invites over the year:
• Socceroos game in Canberra (sold out before I could reply)
• Teddy Swims concert in Sydney (no interest)
• P1 Dinner in Canberra (unable to attend due to travel)
• Art exhibition tickets in Canberra (no interest)
• CL invite on a SYD-CBR flight (gladly accepted even though it was a 5am lounge visit)
I received a couple of hand-written thank you notes on F flights recognising my P1 status, and had my meal order taken first on one occasion when seated in Row 3 of a domestic J flight.
I started getting an escort to and from the lounge in SIN when in F which never happened as a WP, and I haven't needed to argue with the SYD lounge staff about the special menu and seating area when flying QF F as I had in the past when just a WP.
I now tend to get pre-allocated 1A on the Dash-8 the vast majority of times I fly, though I prefer to swap to 2D as the overhead bin above row 1 isn't available for passenger use. As a WP I'd get anywhere between row 3 and 8, and wasn't able to select the front exit rows at all.
The call centre experience has been the most noticeable change compared to WP, both in terms of wait time and their ability to action requests. I only applied for classic award availability once, F return to the US, and was approved for all of the flight options and dates I asked to be considered. I used the 'upgrade request for a family member at P1 priority' once, for a domestic transcontinental Y->J return, with both legs successful.
