It's blowing up heaps on social media.
Many of them comparing to JQ et al (i.e. LCCs where any toilets can be used by any passenger), lots toeing the "Business fat cats getting their private toilet while everyone in Economy getting utterly <insert word here>" line. I don't know if I should be surprised or not as the topic of toilet ratio has never really been a hot one for goodness knows how much.
Feels a bit like the story of a student who is an utter failure because they got A grades on everything except one subject is a C (not saying QF have kicked lots of goals here, but that seems like the nature of the stories latching onto the toilet thing).
The Asian carriers (well, legacy ones) actually do well in terms of toilet to pax ratio (including in Y), but their toilets actually get used quite a bit. I can't remember the last time I tried to use a Y toilet on an Asian carrier and the wait was at least 2 people deep (including the one in the toilet). Maybe Asians have quite different habits to us, or is it a weird case of "build it and they will use"?
