Additionally, United will introduce new routes from Denver to Punta Cana, Dominican Republic, and Mexico City, Mexico, starting October 26, 2025. The Mexico City route will function as a winter seasonal service, while Punta Cana will be served nearly year-round. These changes increase United's international destinations from Denver to 22, the highest in the airline's history at the airport.
