In general, if I am traveling internationally with (in order):
- Domestic flight,
- International flight,
- Domestic flight,
all with different airlines, will I have to pickup and drop my luggage multiple times? And go through security multiple times? And where will my passport be checked: before 1) or before 2)?
Is it different if the airlines are the same? Is there a "common rule" or could there be exceptions?
I need to travel internationally through JFK and there are many options, with many airlines and different layover times. I need to know what I will be required to do, because some layovers are very short (50 minutes) and the time may not be enough.
