Salt Lake City International Airport (SLC) has been named the top airport in the United States based on on-time flights. Cirium stated the airport had an on-time departure rate of 83.80% and an on-time arrival rate of 84.78%. 
Delta Air Lines also led US-based airlines to be the most on time (most of the flights at SLC are Delta-operated). This follows on from 2023, when Delta also led in US Department of Transportation performance.
