GIG-GRU/GRU-JFK: Connection on different Airlines
I am returning from Brazil this coming week. I am flying from GIG to GRU on TAM airlines and then from GRU to JFK on Delta. When I arrive at GRU, will I need to exit security, check-in at Delta, and then go through security again? The GIG to GRU flight is a domestic flight and not connected with the Delta itinerary.
