Upgrade using Avios on London City to New York
Hi all,
I was wondering if it's possible to upgrade using avios from WTP to Club World on the London City Service? I suppose this would have to be done at the time of booking?
If not, does anybody know if it's possible to buy a WTP ticket on a LHR or LGW route, upgrade using avios to club, and then change to depart / return to LCY instead?
Many thanks
