United or alaskan ?
 

I have recently purchased a business that will alow me to charge around $70,000 a month. My question is for everyone out there ( new user here ) What miles card should I be using ????
1) I live in a small market we only have united, alaskan air.
2) Because I live in a small market flights can be very expensive anywhere
3) I was told that I want to earn miles , not points
4) both airlines have about an equall amount of flights in and out
5) I have heard about the united merger and am not sure if thats good or bad


Any help with this would be greatly appriciated :)

thank you
