Difference Between Pvg And Sha

I know some difference between PVG and SHA.
1.Hong Qiao Airport (SHA) is much nearer to the city than Pudong Airport (PVG). SHA is on the west of the city and PVG is at the far-east. A20 is the outter ring of the city. SHA is exactly located at west part of the ring while the PVG connects to the A20 via a highway A1. You get the idea, right? Refer to the map.
2.Hong Qiao Airport (SHA) is older than Pudong Airport (PVG). SHA was the first airport in Shanghai. PVG was built when the expansion of Hong Qiao Airport became impossible when the city grows and surrounds the airport. The equipment of Hong Qiao Airport became old while PVG is brand new.
3.Hong Qiao Airport is for domestic flights only. Pudong Airport serve both international and domestic flights.
4.Pu Dong Airport is bigger than Hong Qiao. With the second run way constructed, it aims to be an international aviation hub like Tokyo or Hong Kong.
5.Pu Dong airport has MagLev connected to the Metro Line #2. There is no Metro or Maglev for SHA.
