Though United is adding frequencies across its short-haul international network, none of the routes are actually new for the carrier. Instead, the airline is either resuming temporarily suspended service or extending the season on other limited-time flights. Nevertheless, United’s currently offering 32 routes to Central America, more than any other U.S. airline.
