Great tip about wifi at GRU. Can anyone give a few more details about the 'light meal'? The thing is that I'm doing the trip both ways in CW as well (upper deck too so quite happy) and on the outbound, I'm wondering whether to skip the breakfast presumably served before landing at GRU if the light meal would make up for it? But then if it is just a sandwich or an 'extended breakfast' equivalent, it might be worth waking up if a full breakfast is served!! Any other tip would be welcome (as would a link to the trip reports mentioned above - I speak Spanish!) Thanks!!
