I made about 12 intra-chinese flights in the last 24 months.
All but one on paper tickets.
I had e-ticket from Shanghai to Beijing-Guilin- Shanghai.
My Chinese friend made an e-ticket resevation for me.

Getting out of Shanghai was a hassle. Leaving for the airport in Beijing I noticed that my friend had the wrong date on the ticket it was yesterday's date.
Try explaning that to the clerk.
She said my name was in the computer but no ticket attached.
I had to purchase a new ticket and they only had only first class left. no refundsor credits on the e-ticket.
If I had a paper ticket they would only chage a small fee for the date change.
Getting out of Guilin was a hassle too, they had to print a paper ticket for after waiting 20 minutes.
