Can I buy the tickets for CRH train in advance at Chengdu airport?

Yes, there is a ticket office at the Gate 1 of the domestic entrance in Termial 1. It is in service 08:00 - 18:30.

thank you Jack.

Can I also buy the CRH train (High speed train) ticket for 6 days advance?

What is your destination? Usually, it is suggested to book the ticket around 10 days in advance in case they are sold out.

I will arrive Shuangliu airport on Septemberber24, and I plan to take high speed train(CRH) to Chongqing on September 30.

From the airport , I will travel direct to Ya'an by bus (from long distance bus staion near the airport.

So, I would like to know whether I can buy the Crh train ticket from the airport or not.

Oh, it is during peak season, so it would be best to book the train tickets online in advance. All the tickets may have been sold out when you arrive at the airport. Hope it is not late to book the ticket. Hurry up!
