It seems they were cleared to FL 370. What FL do you think they should have flown, given this clearance?
Me? I don't know. I only read leaked reports, and translate to you. But for us, Brazilians, this clearance has a completely incorrect format. It should mention Brasilia and Teres. Experts say that the crew shouldn't have accepted this clearance, until ATC tell the complete route. The way it is, it seems that they should go straight to Manaus, FL 370, and not passing through Brasilia and Teres.
