Hi, Adam,
Thank you very much for your enquiry.
Generally speaking, there are 2 less costy ways from Pudong International airport to Hongqiao Airport.
1. Subway (06:00-22:00)
Metro Line 2 from Pudong airport to the T2 of Hongqiao airport.
Metro Line 10 from Pudong airport to the T1 and T2 of Hongqiao airport.
The subway train departs every 8-10 minutes.
Shuttle Bus (07:00-23:00)
Shuttle bus No 1 from Pudong airport to the T2 of Hongqiao airport and Hongqiao railway station for high speed train. The shuttle bus will depart every 15-25 hours and the cost is around RMB30 per person. It is not reserved but buy the ticket at the spot.
Compared both ways, we do suggest subway as it will not suffer traffic jam, alther it might be a bit crowded on the subway train. But it will not waste time on the way. If yo do not have many time for the transit, subway will be first choice.
If you have more time and hope to be more comfortable, the cost will more. You could choose to take taxi or book private transfer with local travel agency from Pudong airport to Hongqiao airport or railway station. To be honest, it is not suggested.
Hope the above is clear and helpful.
Should you have any question, please do not hestiate to cotnact with us.
