Getting from downtown to Changi Airport via MRT turns out to be extremely easy, and amazingly cheap. It was $1.50 from City Hall, and took less than 40 minutes from station to station. You have to change at one point, but that just means walking from one side of the platform to the other.
The taxis are pretty cheap– my ride from the airport to my hotel was less than $15, if memory serves– but the subway is definitely better. Even easier than taking the Underground to London, or the El out to O’Hare, to say nothing of the Caltrain-BART two-step to SFO, or the Metro-Washington Flyer combo to Dulles.
Why every major airport isn’t directly accessible by whatever the dominant form of public transportation serves the nearby city– why this isn’t an IATA mandate or such– is beyond me.
More generally, I love the MRT, the Singaporean subway. It’s relatively cheap, very fast, air-conditioned, and the stations are really nice. Plus just about every square inch is chrome or a flat-panel monitor, so it’s great for those of us who have short attention spans. I bought a lot of one-way tickets, but next time I’m here I’ll have to figure out the passes.
