Only 3 hour’s transition time from Pudong Airport to Hong Qiao airport? Is it enough? Let’s calculate.
It takes 10 – 30 minutes to pass the custom. Depending on your position in the long line waiting at custom. So 40 minutes should be a safe bet.
The airport bus line #1 connecting Pudong and Hong Qiao airport operates at interval of 20 minutes (15 minutes in rush hours). So plan for 20 munites for waiting the bus.
The bus should arrive in Hong Qiao in about 1 hour. This is relatively precious estimation because there is no single red light during the road and the bus runs on the Expressway. There should be no traffic jam.
Hong Qiao Airport
Leave at least 20 minutes for you to find the ticket counter, buy the airport construction fee. Also, all domestic flights at Hong Qiao Airport require you to arrive 30 minutes before the departure of the flight. That is 50 minutes.
So, to be safe, you need to leave 45 (custom) + 20 (bus waiting time) + 60 (bus time) + 20 (Hongqiao Transition) + 30 (before departure) = 175 mins (3 hours) between the two flights.
What if I only have 2 hours?
If your flight arrival time in Pudong Airport is only 2 hours ahead of the flight departure time in Hong qiao Airport, chances are, you will miss your flight. However, if everthing goes very smooth, it is not a mission impossible. For example, if you rush out of your plane as the first passenger and use only 5 minutes to arrive the custom gate and pass it, and catch the air port bus in the next 10 minutes (which is possible). 1 hour later, you are already at Hong Qiao airport and you use 5 minutes to get off board the bus and find your counter – you can make it in 1 hour and 20 minutes. It is possible, if you are lucky enough.
