One last question to all the experts here -- would you recommend crediting the flights to AA or AS? I saw that AA has done a large devaluation of earnings and it seems like AS is still doing mileage flown plus a 2x multiplier for business fares.

Calculating it for our itinerary, I'm getting AA would credit about 40k while AS would credit about 100K.

This seems like a no brainer to credit to AS.

Is there anything I'm missing here?

Thanks again everyone for all of your help and for creating this amazing community. I'm super appreciative - this trip wouldn't have been possible without it!
