Hello, i have a business trip in January 2010 starting with return flight from London to Shanghai Pudong on 9 Jan (arrive 10 Jan). Then on 10 Jan i will fly from Shanghai to Seoul for 4 days before rteurning to Shanghai on 14 Jan 2010. I think i will probably have to fly from Hongqiao Airport on Shanghai Airlines. How should i travel between Pudong & Hongqiao Airports, easiest route? And is there a transfer process to make it easy?
