Singapore is served primarily by Changi Airport (SIN), a major international hub known for premium facilities, numerous long‑haul carriers and an extensive low‑cost airline presence; Seletar Airport handles some regional and general aviation flights but is more niche. Changi sits about 17–20 km east of the city centre, with the MRT Airport Line taking roughly 30 minutes, taxis typically 20–30 minutes depending on traffic, and private transfers or ride‑hailing similarly timed — expect fares to range from modest public transit prices to mid‑range taxi or ride costs. Changi’s strengths are convenience, wide onward connections and plentiful amenities; cons can include longer walks between terminals at peak times. Seletar can be quicker for close‑in regional hops but offers fewer scheduled options.
