The old St. George Municipal Airport, located on top of a mesa, was land-locked and had no room for expansion.

The new St. George Regional Airport (37°02′11″N 113°30′37″W / 37.03639°N 113.51028°W / 37.03639; -113.51028 (St. George Municipal Airport (2011-present))) was built about 6 miles southeast of downtown at the site of an abandoned airfield, which had not seen air traffic since 1961 and most recently has been used for vehicle drag racing and radio controlled aircraft.

Plans for the new airport include a single runway usable by regional jets and larger airliners.

In the year ending November 30, 2008 the airport had 62,210 aircraft operations, average 170 per day: 72% general aviation, 15% air taxi, 13 scheduled commercial, and <1% military.
