Which cities were in all of the Die Hard movies?

All of the "Die Hard" movies primarily take place in two cities: New York City and Los Angeles. The original film, "Die Hard," is set in New York, while its sequels, particularly "Die Hard with a Vengeance" and "Live Free or Die Hard," also feature significant scenes in NYC. Meanwhile, "Die Hard 2" occurs at Dulles International Airport in Washington, D.C., and "A Good Day to Die Hard" is set in Moscow. Thus, New York and Los Angeles are the recurring cities across the franchise.
