@ Radeng and anyone else asking similar questions about offloading of men.
This is what I wrote in a similar thread in another part of Pprune...
The fact of the matter is that the rule states that UM's cannot be seated next to "Male passengers travelling alone"! No male passenger needs to be moved or offloaded. It is actually up to the checkin agent to ensure when the UM is being allocated a seat that it is next to a female. What happened on board this flight happened because the crew member WAS IN THE WRONG. This man was NOT travelling alone so therefore does not come under the ruling AND even if he was, the rule does not state that the male needs to move, the crew member should have used some cop on and just move the kid without causing any fuss or even needing to reveal the rule.
Every company has idiots like that who both get the rules wrong and seem to glee in imposing their version of the rules on others...suppose its a power trip thing!
