Seletar Airport now operates as a general aviation airport, mainly for chartered flights. As of 2007, the only scheduled services operating from Seletar are Berjaya Air's flights to Tioman and Redang. It has a single runway and 27 aircraft stands, and is opened 24 hours a day.
In 1998, Seletar Airport received 7,945 scheduled flights altogether, handling 23,919 passengers and 6,025 tons of cargo.
The Republic of Singapore Flying Club, Seletar Flying Club and Singapore Flying College are situated at Seletar Airport. The Singapore Flying College also conducts its flying training at Jandakot Airport in Perth, Western Australia and at Sunshine Coast Airport in Maroochydore, Queensland.
Another prominent flying school is the Singapore Youth Flying Club, which has its headquarters built on western side of the airport's runway. Completed in June 2001, the clubhouse also has its own parking bays for its fleet of Piper Warrior II and CT-4E.
In 2007, JTC Corporation announced the plan to upgrade the Seletar Airport to support the upcoming Seletar Aerospace Park. The plan includes the lengthening of the airport's runway from its current length to 1,800 metres and the upgrading of its avionics systems to allow bigger aircraft to land and take off.
