American Airlines and Southwest Airlines had almost 30 percent of their flights arrive late in July, according to a government report released Tuesday.
The North Texas-based carriers were near the bottom of the on-time arrival list posted by the Bureau of Transportation Statistics. American’s on-time rate was 70.7 percent while Southwest’s was slightly higher at 70.9 percent during the busy summer travel month.
Southwest also had the second-highest cancellation rate among U.S. carriers with 2.9 percent of its scheduled flights canceled in July, partly due to a computer systems outage that caused lengthy delays and hundreds of cancellations.
As a group, U.S. airlines posted an on-time arrival rate of 75.2 percent in July, down from 78.1 percent in the same month last year. Alaska Airlines had the best on-time arrival rate with 89.4 percent of its flights on time, and Frontier had the worst with only 63.3 percent of its flights getting to the gate on time.
The Department of Transportation said it received 1,963 complaints from travelers in July, down 9.4 percent from the 2,166 filed in July 2015. Carriers also reported a mishandled baggage rate of 3.32 reports per 1,000 passengers, up from a rate of 3.16.
There were also 11 domestic flights with tarmac delays of over three hours. Delta had six flights with lengthy tarmac delays and American had one, from Detroit to Phoenix, that sat on the tarmac for 199 minutes after it was diverted to Tuscon.
