My friend is flying SFO-NRT-GUM-YAP tomorrow, the connection at GUM is 45mins. The UA apps showed that NRT-GUM, and GUM-YAP using the same plane
Q1: Does passenger go through border control at NRT or GUM? The agent on the phone told her that border control is at NRT. just want to make sure that is the case.
Q2: If passenger doesn't need to go through border control at GUM, can the passenger stay on the plane? or they have to get off the plane and get back to the plane again.
Q3: Is it possible that if NRT-GUM delayed, and GUM-YAP switched to a different plane? Therefore my friend will miss the connection and stuck on GUM.
