Which do you have earning power on? Do you use your Chase cards so you can earn back points via spending? Do you use the AA credit cards to earn?
In general the lower miles & taxes looks good but if you use the 150k onAA that leaves you with 60k remaining which can be two domestic RT tickets or used towards a international ticket. UR has more redemption possibilities so they're more valuable.
Your wife is wise. AA is 10 abreast and CX is 9 in Y. Along with better service.
