Fair point, my example was intra-Europe but outside of Schengen, and henceforth I presumed the same would apply. In any case, if rechecking baggage is required, and on the same airline within the same airport, just shy of 3 hours should be sufficient.Yes, but San Pablo is in Brazil. The accepted practice AIUI is that immigration and customs are dealt with at the first point of entry to the destination country. Imagine what would happen if they carried an individual all the way to Cordoba and only then discovered that they were to be refused entry to the country?
It’s the airline’s responsibility, if I’m not mistaken, to not allow a trip booked on a single trip if it transit isn’t reasonably seamless, and to provide information as to rechecking baggage if required
