I had to fly to MEL on the weekend, travelling with a suit bag (containing a jacket only). BNE-MEL on VA (as Gold), and MEL-BNE on QF (as Plat)... this was my experience:
BNE VA Lounge: asked if there was anywhere I could hang my coat and the lounge angel came around and took it from me, and hung it up in the cupboard behind the service desk. She politely said in a playful way "just don't forget it when you leave".
BNE-MEL VA flight (seated in row 5 - had used Fly Ahead so no row 3 available): handed the CSM my BP on boarding. After briefly looking at the BP, she said "if you'd like to hang that up, just hand it to Marcello and he'll take care of it for you". Plane was a BSI 738, so it was hung on the bulkhead behind 2D. Couldn't have asked for more in either situation.
MEL J Lounge: asked the same question and the lounge angel said "hmmmmmmmm... well I *suppose* I could hang it back here, just please make sure you don't forget it when you leave". Fair enough - no complaints there as it was better than holding onto it!
MEL-BNE QF flight (seated in row 4 with a shadow): handed the CSM my BP, and politely said "I don't suppose you have any room in the closet for my jacket?". Was met with a "no, there is no closet on this aircraft type. You'll need to wait until everyone has put their bags up and then try and fit it on top."... This was a 738, so there was indeed a closet... pretending (particularly to a WP that knows QF aircraft layouts and features quite well) that no such cupboard exists is simply poor customer service. I am aware that the hanging of jackets is officially a J service/benefit, and if the closet was full with J jackets I would have completely understood. I would have also happily waited until all J jackets were in the closet to see if there was still room, though from what I could see, only one jacket was put into the closet on the flight (I saw her take it from the pax after I was sitting down, and return it before landing), so there would have been plenty of room... My issue here isn't so much her refusal to hang it (or allow me to hang it - as it's not something I 'expected'), but rather that she flat out lied to me. I'm tempted to flick QF an email, though I doubt they'll really do too much (as even if they do tell her not to lie to passengers as has been mentioned earlier in this thread, she seemed very set in her ways (was an older CSM), so I doubt it would really achieve anything)... a shame really, as I was looking forward to this flight (first QF flight as a WP), and the CSM managed to put me in a bit of a crabby mood before even reaching my seat... the rest of the crew were fantastic though!
And before anyone asks - I chose not to challenge her on the existence of a closet by pointing it out or opening it, as her tone indicated she wouldn't have any of it even if I knew she was lying, so I figured there was just no point in making an enemy of the CSM before take-off haha!
