An updated version of a series of maps I made last year, of states, provinces, and territories in the US and Canada that those two countries' major airlines currently fly to, or plan to start flying to in the future.

Source: flightconnections.com. May not be 100% accurate.

Notes:

• Includes flights operated by regional airlines (Republic Airways, SkyWest Airlines, etc.) under larger airlines' regional brands (American Eagle, Delta Connection, United Express, etc.).
• Hawaiian Airlines flights are included in the Alaska Airlines map as the latter's acquisition of the former nears completion.
• There are no airports within the borders of the District of Columbia. For the purposes of these maps, DC is highlighted (in addition to Virginia) if the airline flies to Dulles and/or Reagan Airports.
