Am traveling this ticket and in Spain right now enjoying my BCN stopover. When I first booked this ticket, there were two options for SCL-GRU to connect SQ67 (departing at 17:50): G3 7661 (6:10-11:00) and G3 9243 (11:00 - 16:25). I was debating which one to choose - for the first option I will have to get up really early and stay in GRU lounge for a long layover, but the second option is too tight. Ultimately I chose the first option.

Just checked back and found G3 9243 at that day was 1 hour late to arrive GRU. I would have missed SQ67 if I chose option 2. So feel quite fortunate to make the right call.
