Sadly, with this extra Shenyang stop, I will have no time to go out in Guangzhou anyway - the layover there is now only 4 hours!
Should be safe then to just tell gtg to keep the ticket as is right, since on the day anyway if something goes wrong, CS will be my point of contact? I assume my ticket is fine now so maybe my best move is to keep completely quiet and not go back to anyone at all...
Just wish I could logon and choose seats!
