Best and worst airports for flight time

USA FActs - A flight is considered on time if it arrives within 15 minutes of its scheduled arrival. In spring 2025, nearly one in four domestic flights did not arrive on time — the worst second quarter for delays since 2014.

Passenger traffic is higher than pre-pandemic levels. As of late September, more than 2.4 million people on average cleared security each day, which was 9% more than in September 2019.

Salt Lake City (SLC) had the best on-time performance of the 30 busiest US airports in the first half of 2025, with 84.4% of flights arriving on time. Los Angeles (LAX), Phoenix (PHX), Minneapolis (MSP), and Detroit (DTW) round out the top five.

Washington Reagan (DCA) had the worst on-time record, with just 67.2% of flights arriving on time. Newark (EWR), Dallas-Fort Worth (DFW), Philadelphia (PHL), and New York LaGuardia (LGA) followed.

Of the 21 major commercial airlines, nearly half scheduled fewer flights in the first half of 2025 than the same time period in 2019. Still, 12 of them had worse on-time performances than before the pandemic.

From April to June 2025, about 2 million commercial domestic flights were scheduled — roughly 3.5% fewer than during the same period in 2019.
