Almost 30 percent of flights leaving North Texas airports in May departed late thanks to heavy rains and high winds that hit the region, according to a government report released Tuesday.
At Dallas/Fort Worth Airport, 70.6 percent of departures left on time while 72.6 percent of arrivals made it to the gate on time. That month, the airport had to close one runway for two days when the rain caused a storm drain to collapse and opened up a sinkhole. DFW officials said the sinkhole wasn’t a major contributor to delays.
The on-time rates at Dallas Love Field were worse: 64.7 percent for departures and 71 percent for arrivals.
According to the Bureau of Transportation Statistics, 14 domestic flights and two international flights had long tarmac delays. Most of the domestic tarmac delays lasting over three hours were at Houston’s George Bush Intercontinental Airport on May 25 when severe weather hampered operations.
Among the top 29 airports in the U.S., Houston ranked last in on-time arrivals and departures. DFW was second-worst for departures and third-worst for arrivals, the report said.
Despite numerous thunderstorms throughout the country, U.S. airlines improved their on-time arrival rate to 80.5 percent, up from 76.9 percent in May 2014.
Hawaiian Airlines had the best on-time arrival rate — 90.9 percent — while Spirit Airlines had the worst — 61.2 percent.
Fort Worth-based American Airlines ranked sixth, at 80.9 percent, and Dallas-based Southwest was seventh out of 13 reporting carriers with an on-time rate of 78.6 percent.
In May, airlines canceled 1.1 percent of their scheduled domestic flights. They also improved their mishandled-baggage rate to 3.09 reports per 1,000 passengers, down from 3.32 in May 2014.
The Transportation Department received 16.4 percent more complaints from consumers for a total of 1,492 in May.
