I am proposed two flights with similar times and price, one to Hongqiao and the other to Pudong.
Which one will allow me to reach the city center (say People's Square) the earliest, while not being too expensive?
Seing a map, Hongqiao seems closer.
Pudong has Maglev (fast train) but it seems like Maglev does not go to People's Square, requiring to change to metro.
Wikitravel does not say much about the time metro trains take.
