How crazy is it that in order to fly north (USA) or northwest (Peru, Colômbia, Central America) from Recife one had to first fly south to São Paulo? ....and a lot of people have to do the same. I used to fly between Miami and Recife or even via Manaus, frequently. Surely there is some logic used by carriers still I think there's a huge infrastructure problem, not only in Brazil, where moving people efficiently has not advanced effectively.
