Finally broke the drought tonight.
SYD-MEL, OLCI'd this morning (Seq <20), O class fare (part of the QF Ultimate Amex annual return flight).
Since I printed my BP (which I never usually do), didn't bother with Quickcheck, and decided against checking my bag as it was pretty light. Helped a NB colleague get a BP for an exit row at the J lounge, but didn't think to get them to print one out for me or try for an exit row myself.
Got to the gate early to try and make sure I got some overhead room for my bag. BP did the magic red beep, but the FA told me it was fine and to go ahead. Naturally, I was somewhat disappointed having been trained to look for the magic beep. Boarded, stowed bags and took my seat towards the front of the 763 economy cabin.
Halfway through boarding, another passenger (SG by the look of it) shows me their boarding pass for the same seat as mine. FA took the passes and returned after a fashion with the one I should have been handed after the beeps, and off I went back up the aisle to fight for the little-remaining stowage space in J.
Sorry for a longer post that was probably summed up in the first paragraph, but hey, it was my first ever QF Op-up. The J seat/service really isn't that special on the SYD-MEL commute, but I was happy in principle to finally receive an undocumented 'halo' benefit of getting to WP.
Also goes to show that even though you should never get your hopes up, op-ups really can happen right up until the door shuts.
