hi

im an hour from boarding CO88 PEK-EWR

noticed for the last hour or two that economy was "FULL" and there were 2 names that were simultainiously on the flight stand-by list and on the upgrade stand-by list

does this mean they were moved to biz-first cause of overboking in eco? or something else?

as of now the 2 names cleard the ug list

i asked at check in if there was a chance of overbooking and was told NO
