Frequent flyer programs are for individuals. Generally speaking, airlines don't allow individuals to consolidate their miles, bonuses or not. Fewer FFPs have the family/joint account system. BA is one of those. However, I am not aware of such system in CO.

If you want to transfer miles from one account to another, it's costly and savvy FTers usually don't recommend it.

If CO is the airline of your choice, you probably should look for more promotions and rack up your miles before your big day. You should visit our CO Forum to check out the good finds.

You should also look into this Chase/CO deal, if you haven't taken advantage of it.

Congrats and welcome to FT!
