Adam, (great name - our son's) a couple of things...

1. Welcome to Flyertalk!

2. Congratulations!

3. Read this thread. In it you will find the (arcane, but very useful) details of the Oneworld award, which many of us feel is the best award product going.

4. As it's your honeymoon a business class award would be great. If you won't have enough AA miles (you'd need 160K for both of you) by the time you book (which on that routing shouldn't be something you need to do 330 days out) you could consider buying miles through aa.com.

As you may detect, there's something of a rivalry between AA and BA FTers. But I'm sure everybody wants you and your betrothed to have a great experience. So refer to items (1) and (2) above....
