For work travel do you have a choice of airline or does a corporate policy need to be complied with?

USA based airline ffp's tend to more generous (earn/burn/upgrades/award cost/award cash surcharges/expiry) than non USA based airline ffp's

You could join UA. If you have a non USA address [] you do not have the $$ rules for status. Use your M&M status for the benefits, then change ff number at the gate:- may work or may not

You will not get a status match in the same alliance (i.e. UA)
AA do not match, but offer a challenge
