I am arriving at Hongqiao International Airport late at night 10:30 pm and need to get to Pudong International Airport.

1. Is there are shuttle bus from Honggiao airport to Pudong airport that leaves after 10:30 pm or later as I will have to clear customs etc.

2.How long does it take to clear customs at Honggiao and is the an HINI check there to?
3. How much time do I need to allow to get from one to the other at that time of night?

4. Alternatively what is the cost of a tax between the two and how long will it take?

I'd be grateful for any answers. Thank you.
