In Australia this past week or so there have been news stories about male passengers being moved away from UMs on Qantas and Virgin.
From memory, the Qantas pax was a registered nurse with clearance to work with children - he was humiliated and made to feel like a child molester. The Virgin pax was similarly embarrassed.
The ensuing uproar has led Virgin Australia to place this notice on its Facebook page:
"We understand the concerns raised around our policy for children travelling alone, a policy initially based on customer feedback. In light of recent feedback, we're now reviewing this policy. Our intention is certainly not to discriminate in any way."
Nice to imply that your valued customers are potential sex-criminals purely based on their gender.
