I have a domestic flight from GRU to GIG on TAM that originates in Miami, flight number begins 8. I am arriving earlier that day on UA and was wondering:

- how do i avoid customs and immigration a second time on arrival in GIG?

- Will I have access to the TAM lounge, I'm *G?

- or can I check my gas when I check-in with UA and just do an international transfer?

Thanks,

Dan
