I am in SCL now and the LA people are saying that Air Lingus agent will issue the BP at T4 "transit area"...whatever that means as I need to clear immigration and customs anyway...they seem pretty clueless about this...
I am prepared to haul my luggage to T8 and try to get AA to arrange me through security with my OLCI printed AY boarding pass if they are not able to issue a new one on benalf of AY in the morning...
