MacDill historically hosted an annual air show and "open house" enjoyed by thousands of spectators each year. However, there were no shows in 2002 and 2003 due to security concerns following the attacks on the United States of 11 September 2001 and the initiation of Operation Iraqi Freedom in 2003. The 2006 show was also canceled due to security concerns on base, but was reinstated in 2008. It was cancelled again in 2013 due to defense budget constraints, but was reinstated again in 2014 as a biennial event. AirFest 2016 was the first-ever airshow to feature a live webcast of the performers, including the headline act of the United States Air Force Thunderbirds.
