See the On-Time Performance section for the latest delay data at both airports. This shows departure and arrival reliability to help you plan.
Route data is updated regularly from official airline schedules. On-time performance data comes from recent airport delay snapshots.
Denver sits at 5,280 feet elevation, and PHX summer temperatures regularly exceed 110°F. Combined, these conditions create lower air density that affects aircraft performance on heavy loads. Carriers occasionally impose weight restrictions or reduce passenger loads on smaller aircraft on very hot summer afternoons, though this is uncommon for standard narrowbody jets on this route.
DEN is one of the most weather-delay-affected airports in the US from October through April due to its location east of the Rockies, where upslope storms develop quickly. PHX–DEN afternoon arrivals are most exposed to storm-window delays; early-morning PHX departures typically arrive before conditions deteriorate.
Southwest Airlines typically offers the highest frequency on PHX–DEN, with departures spread across the day from early morning through late evening. United also operates multiple daily nonstops from PHX via its DEN hub. Frontier and Spirit offer lower-cost options with fewer daily slots.
Phoenix to Denver
The PHX–DEN corridor connects two of the Mountain West's largest cities across roughly 950km and a 1.5-hour block time. Six carriers operate over 330 weekly departures. Southwest maintains strong frequency from its PHX focus city; United operates DEN as a major hub and competes with multiple daily nonstops. The route serves both leisure demand (Coloradans visiting Phoenix warmth, Arizonans accessing Colorado ski resorts) and business travel between the two metros.
Seasonal Demand Patterns
Demand peaks in both directions seasonally: Phoenix sees high inbound traffic from October through April when Coloradans seek warmth, while Denver sees high inbound from January through March from Arizona ski travellers. The summer shoulder between June and August is relatively quieter. Denver International's high elevation and exposed plains location make it the more operationally challenging airport, with snowstorm risk the primary disruption source October–April.
