Cancel 2-4-1 booking, use Avios but keep voucher for another time
Evening All
I have a 2-4-1 trip booked to HKG with onward journey on separate ticket next October. Increasingly concerned the trip is not going to happen as transit through HKG is not allowed so want to rebook on a single through ticket using CX all the way.
Can I take a voucher for the existing booking, then only use the Avios and park the voucher for a later date?
