The Brief

• A new report ranked airports nationwide on reliability, based on their rate of cancellations, delays and diversions.

• The majority of the top 10 most reliable airports are in the western U.S. Los Angeles International Airport ranked as the most reliable.

• The majority of the top 10 least reliable airports are in the south, but the report noted that Atlanta’s Hartsfield-Jackson International Airport was fifth most-reliable. Ronald Reagan Washington National Airport, meanwhile, ranked as the country’s least reliable airport.

As the U.S. approaches the busiest travel season of the year, a new report has ranked airports across the country in terms of their reliability.

Big picture view

The report, from Consumer Affairs, ranked airports across the country on their reliability, based on their rate of cancellations, delays and diversions. It used data from the Federal Aviation Administration and the U.S. Department of Transportation to build its rankings.

Data revealed that Los Angeles International Airport leads the nation in flight recovery options, averaging 5.7 alternative same-day flights to the same destination and the lowest share of last-flight-of-the-day cancellations. At the other end of the spectrum, Ronald Reagan Washington National Airport ranked the least reliable, leading the nation in cancellations (2.8%). The data also showed Reagan cancels its last flight of the day more than any other large airport in the country. But the report found that nearly half of the delays are caused by flights showing up late, more than any of the five worst major airports it ranked.

The report found seven of the 10 worst major hubs for flight disruptions are located in the South, but Atlanta’s Hartsfield-Jackson Airport, the nation’s busiest, ranked fifth best.
