Hii all,

This is my first ever post , and I would be grateful if you could help.

I'm flying CX256 from LHR to HKG leaving 20:15, and wondered how easy it was to change to an earlier flight with out paying for it. I will be getting to the airport for 15:00 which is far too early. Anyway I know there is 17:00 CX238 and 18:20 CX250.

Do they give you the option when you check in online, or is it worth going on the charm offensive when checking in at the desk.

Any information or insight will be amazing

Thanks
