I often do this line, 30 minutes or so, Jiangbei Airport to Chongqing North Railway Station, I checked ha, that day just weekend, Saturday and Sunday train group tickets are more nervous, you 14:20 to Jiangbei Airport, out of the station walking to Chongqing North Railway Station, time for you to calculate enough points, probably 15:10. You have to immediately buy a ticket back to Chengdu to the train group is afraid it is too late to see if you can buy a ticket by chance. You can seat the car well, there roar to Chongqing to Chengdu car, also more than 100 yuan, I did. You are in a hurry to do the car!
