Performance can differ sharply between a state's biggest hub and its smaller airports, so airport-level pages are the right place to dig into specifics.

Why the spread? Delays in Utah - as everywhere in the BTS dataset, break down into five categories: late-arriving aircraft, carrier issues like maintenance and crew, National Aviation System constraints such as air traffic control and airspace congestion, weather, and security. The relative mix changes by airport and season: a small regional airport may see weather dominate, while a major hub tends to lean on late-aircraft and NAS delays. For travelers choosing flights through Utah, the combination of a 85.8% statewide on-time rate, 77.0-minute average delay when late, and 0.58% cancellation rate is the concrete benchmark to weigh against specific airports and carriers.
