Are you buying a house soon? You feel comfortable applying for CC?
How many FF miles do you have with CO?
If you have 1 year, dedication, discipline, and some "luck" I would suggest that you and your wife start churning AA CC. Both of you could potentially get 200k+ miles each. Should be enough for a nice trip to Europe for both of you. Alternatively a honeymoon in the Caribbean can be nice too (easier to find use AA miles for this destination).
