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.
