As the second half of 2012 began, Salt Lake City's airport continued to dominate the on-time standings of major U.S. airports.

Of 29 airports tracked by the Department of Transportation, Salt Lake City International possessed the best arrival records both in July and the January-through-July period, with 86.6 percent and 82.9 percent of all aircraft landings on schedule.

The airport also was No. 1 in the same month and seven months of 2011, the department said Monday.

On-time departures were also notable. The airport's 87.8 percent on-time rate in July was No. 1, as was its 90.2 percent performance in the January-through-July time frame.

Last year, the airport was No. 3 in both categories.
