There is an interesting story behind the line here.
Virgin has well and truly seen the end of its Honeymoon period, and is now expected to demonstrate the same level of maturity as any other established business.
With that comes visible adherence to the relevant rules and regulations.
Whether or not they actually do discriminate, Virginblue, no Virgin group, purvey the image of youth and good looks (thier chairman excepted). It is inevidable that at some level there are those who will take unbrige to that fact.
Quite frankly, I think it is great for Qantas. As long as Virginblue continue to push the 'Fembot' image, they are helping to exclude themselves from the high yielding female business market.
