Mileage Plus Select Visa bonus miles earning question
Select visa says:
=====
Earn triple miles for every dollar spent on United purchases
Earn double miles on gas, home improvement purchases, groceries, dining and Star Alliance® purchases
=====
Do I earn triple miles on United tickets regardless of whether purchased through .bomb or operator/reservations call center?
How do I get double miles on Star Alliance purchases? I must purchase on the *A airline's website? Or, do I need to call United and purchase through them? (If I get 2x miles through *A airline's website, could I get 3x by calling united to buy that same *A ticket?)
