No guarantee of better service and facilities but worth a shot. Read yesterday that GIG is now the third-busiest international airport in Brazil, with Brasilia having overtaken it (GRU still #1). Article said BSB had lowered fuel costs, attracting new carriers. I noticed that Delta is now flying 767s from BSB to ATL, vs. 757s. My wife said she read that the air traffic controllers at BSB have a bad rep. I haven't landed at, or taken off from, BSB on an international flight since the days of Transbrasil, when they flew from BSB to IAD and JFK.

Haven't found all that many bilingual services at Brazilian airports, but I imagine it's easier for an American or Brit to get assistance in English in a Brazilian airport than for a Brazilian to get assistance in Portuguese in the U.S., and maybe the U.K.
