Qantas just doesn't get the whole passenger experience thing - which is why they are losing market share. The reconfigured A380 is a disaster and will turn people off selecting QF - BC on Virgin to the USA 1 toilet for 12 pax, Qantas 1 for 25...
"What factors influence choice of airline?"
I'm not convinced: if you ask a majority of passengers (ie not the highly intelligent and informed readership of AFF) "ratio of toilets to passengers" is probably NOT in the top 10 reasons.
Ah, that well informed readership of AFF again....
As an informed reader of AFF, the ratio of toilets to passengers isn't even a concern of mine. Well it kind of was before I flew LAX-SYD on one of the refurbs. Had no issue on the lower deck, not sure about the upper deck though, but one could always pop down to the lower deck via the rear stairs if it starts getting slightly "crowded" on the upper deck.
And as for the pax who aren't avid AFF readers, my family choose tickets based on price and experience. QF was the cheapest for our trip to LOTFAP and so my mum chose that. My aunt has had good experiences on a QF A380 and their QFF program with the points+pay option (I know poor use of points but they're infrequent flyers and any dollars off a sale fare is good in their eyes). After our trip my parents were commenting about how the A380 was a very enjoyable flight compared to all the others they've had in their life time (again this is relative to them). Felt spacious, nice seat room (we're not very big) and the AVOD was nice, especially the tail cam. Overall, my mum now wants to fly QF to LOTFAP because of the A380 product, and TBH so do I.
The only gripe I have with the A380 is the luggage coming out so damn slow... but then with up to 484 pax, one would expect it.
Are there any facts in this post or just opinions ?
Opinion.
On a VA 777 there's 30.08 pax per toilet overall. Or in Y cabin only, 41.14 pax per toilet. (Not sure if Y+ goes to the J toilets or Y toilets... they don't seem to have their own) Also don't forget that one of the toilets in J is female only... so that would add a little bit of a line for the guys.
On a refurb QF A380 there's 34.57 pax per toilet overall. Or in Y cabin only, 46.38 pax per toilet across both decks. On the upper deck only, it's 30 pax per toilet. (I really don't see a problem with the upper deck if the ratio is lower than VA's for the entire plane...) Making the ratio on the lower deck 48.71 pax per toilet.
Overall not a major difference IMO.
And for comparison, on the old config. Overall there's 26.47 pax per toilet. And for the Y cabin only it's 41.5 pax per toilet.
Take what you may from these numbers. IMO IRL this means squat all.
Edit: Just realised this was talking from a premium cabin perspective? If that's the case, where do Y+ go on VA and QF? From the seat maps it seems like Y+ are seated behind toilets that seem like they belong to the J cabin...
