AFAIK = As Far As I Know
AFAIK the restriction is take off ex LOS. SAA cannot take a full load and fuel ex LOS due to runway restrictions, therefore they take as much as possible then go to ACC to top up, spending approx 1 hr on the ground.
I also heard that the overnight work on the runway at LOS didn't finish on time this a.m and a couple of a/c diverted into ACC to await opening.
No idea when the rwy will be properly back on line SortieIII
