Las Vegas and Punta Gorda. Las Vegas service ended in March 2014. Airbus A319s & A320s fly the bulk of Allegiant Air routes out of Plattsburgh. On March 15, 2008, the airport began hosting regular service by Direct Air, offering three direct flights weekly to Myrtle Beach, South Carolina. The charter airline already had a successful service to Myrtle Beach from Niagara Falls, which has drawn many passengers from Ontario just as Plattsburgh is now doing from Quebec. On April 29, 2011, the airline announced it would offer two non-stop flights per week, departing and returning on Wednesdays and Saturdays, to Lakeland Linder International Airport beginning November 10, 2011 using Boeing 737-400 aircraft. The reason Direct had chosen Lakeland as its latest destination was its proximity to both Orlando and Tampa. Direct Air planned to make flights to and from San Juan, Puerto Rico, starting on May 2, 2012. On March 13, 2012, Direct Air ceased operations. The charter carrier was subject to Chapter 7 liquidation on April 12, 2012. The airport was served by Colgan Air until June 14, 2012, offering up to three flights daily to Boston on a variety of turboprop regional airliners.

PenAir was selected as Colgan's replacement and offered to two daily flights to Boston, subsidized by the Essential Air Service program. The airport was also served by Spirit Airlines with non-stop service to Fort Lauderdale and seasonal non-stop flights to Myrtle Beach. Also, it was reported on January 13, 2012, via WPTZ that the airport was planning on expanding by building a new two-story terminal with six additional jetways, along with expanded parking, ticket counters, baggage claims and security checkpoints which is estimated to cost more than $40 million. On September 18, 2012, the airport received more than $6.5 million in federal grants to use toward infrastructure improvements that should start early 2013. Champlain Enterprises successfully restored a vintage 1943 Douglas DC-3 aircraft, which made its first post-restoration flight on June 2, 2006. The aircraft was housed in the former Plattsburgh Air Force Base Auxiliary hangar on the south side of the airports tarmac. It made regular
