Train from Chengdu airport to Chengdu East Railway Station

Ten pairs of rides are available daily from 07:30 to 20:45 between the station and the airport. The travel time is about 16 - 22 minutes and the ticket fare is CNY10 for a first class seat and CNY8 for a second class seat.

How frequency? And where to board the ride?

I have a plan to go to Chongqing from Chengdu airport. This info will help booking.

Thank you.
