I was booked a flight with a connection in Sao Paulo, Brazil. However, I noticed that I will have to transfer between airports between the domestic and international legs of my trip. They are all on the same reservation, but I have a relatively short connection (4h) and traffic in Sao Paulo can be very chaotic as I recall.
I know that airlines will put me on another flight if I lose a connection in the same airport, but I have no idea if they would do the same if I lose it because of an airport transfer.
Anyone had any experience with this?
