How much savings do you need to forsake earning miles?
looking at a ORD-CUN trip. USA3000 has nonstops for $375. AA has one stop for $422 and United has nonstops for > $600.
I'm not aware of any loyalty program for USA3000.
Would the savings and nonstop be enough to convince you to forgo the potential mileage earnings?
I'm strictly a pleasure traveler with no status, although I do like earning miles.
