[1] Today, Seletar Airport mostly serves turbo-prop and smaller-sized private and business jet airlines and aircraft.

The airport is currently not capable of handling larger airliners such as the Boeing 737 or the Airbus A320 family, as it will need an upgraded runway and avionics system in order to accommodate aircraft of those size.

Seletar airfield was the target of carpet bombing when Japanese navy bombers conducted the first air raid on Singapore, sometime after their ground forces invaded Kota Bahru.

21 Squadron, Royal Australian Air Force was also based at Seletar in 1941–42, and was in the process of converting from lightly-armed CAC Wirraway trainers to Brewster F2A Buffalo fighters, when hostilities began.

The 601st Kōkūtai was also stationed there for training early before its destruction on board Japanese aircraft carriers during the Battle of the Philippine Sea (Marianas Turkey Shoot) in June.

From June 1962, 66 Squadron (led by Sqn Leader Gray) with their Bristol 192 Belvedere helicopters were also based at Seletar, and were sent on frequent tours and detachments to Kuching, Brunei, Labuan and Butterworth as part of the Borneo hearts and minds campaign (the squadron was later disbanded in March 1969).

[5] The RAF station closed at the end of March 1971 (see East of Suez) and Seletar was handed over to Singapore's Department of Civil Aviation.

[6] Several aircraft types flew their last RAF operational sorties from Seletar including the Short Singapore flying boat (Mk.III K6912 of No.

The subsequent arrival of eight new Cessna 172Ks in May 1969, took over the duty from the former and contributed to the increase of training tempo for more selected trainees to participate in the basic flight-training course.

[10] As part of the Seletar Aerospace Park programme, the runway was extended to 1,840 metres in 2011 to enable larger and heavier aircraft to use the airport.

[14] The terminal houses four check-in counters, six immigration lanes, two security screening stations and a gate holdroom that can accommodate 200 passengers.

It has a single runway with 27 aircraft stands, 100 square metres of warehouse space and can handle 840 tons of freight per day.

In 1998, the airport recorded receiving a total of 7,945 scheduled flights, handled 23,919 passengers and 6,025 tons of cargo.

The renowned Singapore Youth Flying Club has its headquarters built on western side of the airport's runway.

[22] Due to the COVID-19 pandemic, the number of daily commercial flight operations at the airport severely declined.

Airport operations were also subjected to new processes and rules laid down by the Singapore government Ministry of Health and according to the Infectious Diseases Act.

Passengers heading to Changi Airport can alight at the Jalan Kayu roundabout and transfer to bus 858.
