Anyone know the answer. The answer from VS on the phone in the US was no, but then she didn't know what it was in the first place. Certainly there are no mentions of APD on the US or UK version of the VS site, and a search turns up pages that are no longer displayed.
I'd be very surprised if they aren't still collecting it. No official people asking for it, there was just a note against our booking when we were checking in and the agent clearly marked on our boarding cards that it had to be paid so we wouldn't have been able to board without doing so.
As you say there is nothing on the VS site about APD now so maybe an email to FC or just be prepared to pay it and if you aren't asked, then lucky you!
