Rebooking fee for Air China

2018-04-27 08:46:32

I would like to book an international return ticket with Air China.

The outbound date is settled, the inbound is not and can only be decided after the outbound travel. Do I may need to rebook the second leg after consuming the first leg. The ticket booking page says 800 RMB for rebooking fee. Also to make things easier I hope to be rebooked on the same fare class. What is the final re-booking fee? Is it as simple as 800 RMB without checking the actual difference in ticket prices (despite having the same fare class)?
