U.S. airlines' on-time arrival rate fell in January on bad weather and late-arriving planes from earlier flights, a U.S. Transportation Department report showed.
The lowest on-time rates were UAL Corp.'s United Airlines, with 62.1 percent; St. George-based SkyWest Inc.'s SkyWest Airlines, with 65.4 percent; and AMR Corp.'s American Eagle at 65.9 percent. Delta Air Lines, which has a Salt Lake City hub, had 78.6 percent of its flights on time.
Among all U.S. airlines, about 72.4 percent of flights arrived within 15 minutes of the scheduled time, down from 73.1 percent in the same month last year, according to the report. More than half of the delays were due to weather and late planes.
The on-time arrival rate was the worst for a January in three years. The results are a setback for efforts at U.S. airlines and aviation regulators to avoid a repeat of last year, the second-worst for delays since record-keeping began in 1995.
