Seems my experience differs greatly from most. 3 years WP, this year about to hit WP+PG.
Most of my travel is domestic Y... so quite a number of flights per year.
Never received an upgrade, don't ever seem to have a 'WP shadow', never received a personal hello... Got a letter last week saying welcome to life time silver though...
I was in 6A last night flying back to Mel on quite an empty 737. All middle seats were vacant back to around row 10 I think. Sure enough some bloke comes and sits in 6B. If everyone in the front half of the plane was WP then I guess it was just unlucky. I doubt that was the case though. Why would they allocate seating like that?
There's been no moment where I've felt WP made any difference to anything. My experience is it doesn't really differ from silver or gold. Still end up queuing in the premium boarding lane with silver & golds anyway.
My experiences are similar to yours. Granted I haven't been WP for as long as you. Though on QF565 they were gracious enough to spill scorching hot coffee all over me. An email to QF managed to get my laundry costs reimbursed. Very generous of them.
