Every U.S. airport with scheduled service has a page. The ones with published route data list every nonstop destination, the airlines flying it, and whether it runs year-round.
Browse airports →Year-round or seasonal
A route that only flies in summer is not much use in February. Every route says which it is, so you know what you can actually book.
