Upgrade Ticket to AP

Hi there,
I will have a 14day ticket from my UK package and know I can upgrade it to an AP. Now my question :slight_smile:
I will perhaps book additional nights when free dining will apply end of the year. AFAIK I have to by at least a 2day ticket to get the benefit. Can I add both tickets to the AP?

Uk 14 day tickets can’t be upgraded to AP. You can only upgrade tickets sold in $ that are on wdw till system in USA.

When did they change this? I (and some friends also) did it in Oct/Nov 2014
