Azul is one of the worst company I have ever flown with. I took two flights in the same week (San Paolo - Manaus, Manaus - São Luis) and both were changed. The first was changed two month before, so ok but we lost a whole day. The second was changed 8 hours before living Manaus and it was postponed 10 hours later. So we lost an other whole day, without hotel in Manaus and in São Luis.
The Azul's staff in manus was completely inefficient instead the staff in São Luis helped us.
The last thing but not the least.. I took 2 flights, 10 hours each, with 5 stairs and I ate ONLY chips and candies (lunch, break and dinner).
