Later then CX123 & CX124 only available on Y which is more expensive! What if CX125 & CX126 on the same day but different dept. time availiable the cheapest K class. Can I buy it then redeem my original U booking i.e. CX123 & CX124?
Thx again to all!
It would be risky, and I will not recommand you to do so. You would need to find another pair of flight that has both K and U availability. Plus, you need to ensure that you can change your ticket to those flight. If all you need is an extension on TKTL (Ticket Time Limit), you might want to just call CX and ask.
