T2 lounges
Similar issue for me. I'm landing on Qatar Business in GRU T3, with a TAM domestic flight from T2.
I did a similar transfer from AA First to TAM domestic last year, and thought I made a mistake in going through T2 security. T2 Wing D was barren! Half the shops were shut and it was late morning, and no lounge.
Was hoping I just missed something either in T3 or before security. Sad that TAM has nothing here, when at SDU they have a small but functional lounge.
