Because when needs must........
Attended the Robbie Williams concert here in
MEL just before Xmas (hey, it was a prezzie for the wife
OK?). 90% of the audience was female - tough job but.... - so the "Ladies" just could cope. The "Gents" had a line of women to the cubicles and out of the door.
Once upon a time it might have mattered to have separate "closets". I don't think we need that distinction anymore and - as has already been mentioned, why lower revenue (fewer seats) and increase costs when no-one really cares?
As an aside - and I'm NOT looking at anything racial etc here - do airlines that are clearly aligned with certain religious practices operate separate Lavs??
