Is there any way to gauge the chances of a person with a buddy-pass getting on a payload optimized flight? One of my in-laws is trying to get to England (lives in US) but he's currently in Bogota on a trip visiting his in-laws. The flight from BOG-ATL says it's payload optimized, so I don't really know if I should tell him to buy a ticket back to the US, and I'll book a buddy pass to England from there, or if he could save the cash and fly standby back to the States on the way to the UK. Anybody have relevant experience/guidance? Thanks!
