Wow .. a lot of work eastwest .. a handy evolving reference, thanks. I know there must be reason for these below being omitted, or maybe just could be added where applicable, as "metropolitan" is such a loose term these days, and as you have EWR and NY grouped, even tho they are different states, likewise IAD/BWI/DCA these might all apply:

LAX-ONT-BUR-SNA

MIA-FLL-PBI

SFO-OAK-SJC

Osaka - KIX-ITM

Buenos Aires is EZE (Eiza) and downtown one which is ???
