2 questions on the QF A380 with Y class in the upper deck;

i) Does anyone know the registration number of the aircraft/s with the said configuration?

ii) From a disembarkation perspective, who will be out of the aircraft first; a) The pax sitting in Y class row 50 - 55 or, b) The pax sitting in Y class row 32 - 36 (upper deck)?

i) looking at seatmaps on QANTAS.com it lists  OQD/OQE with Y/C upstairs

ii) I think I've heard Y/C upstairs follow behind J/C and P/Y pax and disembark via front left upperdeck door...Y/C downstairs disembarks via second left lowerdeck door (if there are 2 maindeck airbridges in use) or follow behind F/C (if only 1 maindeck airbridge in use) ...plus the factoring in of how quickly each airbridge gets positioned/opened and how quickly pax ahead of you disembark!!.. so i spose it isnt an exact science..

hope this info is of some help

Row 50-55 would almost definitely get out before upstairs Y. Even if you have to wait for a full First cabin to disembark (although QF does use a dedicated First bridge when there is one), there are only 14 people ahead of you to use that door, while upstairs you'll have to wait for up to 100 J/P passengers to get off ahead of you... 

Thanks for that guys!
