I can get from my apartment on line 1 to Pudong Airport in 50 minutes with the subway to Maglev combo if I end up getting to Longyang Road station right as the maglev is boarding. Nothing is faster than this and I even have to transfer at people's square. Taxi drivers are falling asleep half of the time I take a taxi so I try to avoid them. I know Moondog isn't a fan of my maglev shuffle routine but in 10 years of doing it I've never once missed a flight and I only spend 44RMB each time! If you're going to end up anywhere near a subway station in town then the Maglev to subway is my recommendation every time.
