I know you need to go through customs. But why do I need to pick up my bag, leave the airport, and go back into the airport?
For example international transfers in a major airport like Frankfurt you do customs but you don’t see you bag and you don’t basically leave the airport.
In Newark you go all the way out to where people are being dropped off for departures at the curb!
It’s airport specific. Not every airport in the US operates this way. JFK may require a complete terminal change.
You do not have to do this at most US airports. New York City and Newark in particular is a special case of bullshit.. I avoid that place at almost all costs. There’s a reason those tickets are cheaper.
But it’s complete in other countries? I guess they pull you bag back out of the system if needed in other countries. Optimise for the common case if not needing to look in your bag.
