There will be sooner or later an attempt to challenge and remove faith based belief as a reason for female people to not be able to access mixed sex spaces, as this is one of the lingering barriers. And this agenda is well served by the culture of religion being all a bit silly and 'other', not helped at all when entitled men behave like this.
So would like to state, for the record, there is a radical difference between demanding to control a mixed sex public space to fit with your beliefs and someone who will not be able to use a designated single sex space where they will be getting undressed if that space is turned to mixed sex. Particularly when a call to the airline in advance to discuss this probably could have ended in planned arrangements that meant no hassle for anyone.
Women get it coming and going don't they? They must be moved to avoid offending males, and I bet no one asked those women how they identified and what their gender was: because this is a sex based issue. Females whose beliefs and cultures will mean they can no longer access loos, changing rooms, gym sessions etc are also not only representing their own beliefs but may have partners, relatives, communities who will not accept or even punish them for not maintaining sex segregation. Many single sex things like yoga, swims, were created to enable these women to have more participation in the community, to have more independence and freedom, and as male people identify into those single sex sessions they push those females back and cause them losses.
And I've heard the let them eat caking from a certain women's officer, who said in essence that those women should just leave the religion and stop believing in patriarchal stuff like that..... words fail at the sheer privilege and naivety. Women are caught on both sides, between males wanting to serve their own interests. It's a sex based problem. And its one that male people don't get and can't understand because it doesn't happen to them.
