About this route
Denver to Houston flights
Denver to Houston connects two major United hubs, making this route a priority for the carrier with high frequency and wide aircraft selection. Southwest and Frontier add competitive pricing pressure. The route serves energy industry business travelers, families visiting relatives, and cruise passengers connecting through Houston's port.
Houston's Gulf Coast weather can bring sudden thunderstorms that halt ground operations at IAH, especially in spring and summer. Denver's own afternoon convective activity means both ends of this route are delay-prone. Landing alerts are particularly valuable when storms are in the forecast at either airport.
