With a credit card voucher you are restricted to routes on BA aircraft.

HNL is out unless you fancy buying a ticket to a BA base ie DFW, ORD, LAX.

BA aircraft operate from all over the USA and the world but all will operate through London by the very nature of them being British airways.

From the west coast of the USA your probably looking at SFO, LAX, SAN, MIA, etc etc etc.

If however you take the companion voucher out of the equation you can use you avios on any one world airline and some partner airlines, around the USA AA is your friend domestically, Alaskan is also an option.

If your looking at Europe you might have some luck with EI via DUB but again that wouldn't allow you to use a companion voucher.

How many avios are you trying to use ?
And have you read the sticky on the BA ft page ?
