Arnold Palmer Regional Airport is a public airport two miles southwest of Latrobe and about 33 miles southeast of Pittsburgh, in Westmoreland County, Pennsylvania. It is owned by the Westmoreland County Airport Authority and was formerly Westmoreland County Airport.
Federal Aviation Administration records say the airport had 18,946 passenger boardings in calendar year 2008, 15,482 in 2009 and 6,978 in 2010. The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a primary commercial service airport based on enplanements in 2008, but it qualifies as a non-primary commercial service airport based on enplanements in 2010.
The airport was served by Northwest Airlink, as a reliever for Pittsburgh International Airport on the other side of the Pittsburgh metropolitan area. The airport also had regional service by US Airways to Pittsburgh International Airport, until the company's bankruptcy. Northwest/Delta ended its daily service to Detroit on July 31, 2009 due to low yields.
In February 2011 Spirit Airlines launched seasonal service to Fort Lauderdale and Myrtle Beach. In January 2012, Spirit announced they would start service to Orlando on May 17.
