Ex Eu flight (with cash) then UuA
A quick question, I wanted to verify something before I book my tickets.
I will be taking an Ex EU flight to HKG in CW (J), I want to upgrade the LHR-HKG leg to First (subject to availability). My understanding is that I have to upgrade the whole flight and not just the LHR-HKG leg? Given that I'll be in CE from EU to LHR is this technically possible to upgrade the LHR-HKG leg?
Thanks in advance
