cherrybim: How do you realistically suppose the best way is to insure one does not get squeezed next to a woman on a 12 hour flight in order to remain in best compliance with S”A EH 21:1?
I think the most practical methodology would be to use the same courtesy request someone needing to ask for a seat change to sit next to a family member placed elsewhere on the airplane or someone unable to sit next to the baby or needing to be closer to the exit to quickly catch a connecting flight.
Last minute seat change requests are a common and accepted possibility.
