Hi

I received a voucher that was issued on 20 July 2015.
I've read the WIKI and it states that the voucher can be used and is valid for travel on American Airlines, American Eagle, US Airways and American Airlines codeshare flights. BUT my voucher states: Valid for travel on AA/American Eagle, American Connection.
Nothing about Codeshares or OW.

So is it possible for me to use in Europe on BA?
Also I've tried to read the information on the link in the wiki but it doesn't work.

Reading different posts here I'm confused by the valid date. Must I travel by the 1 year expiry or just apply the voucher to a booking by then?

Thanks
