Me again.
Maybe the original ones in the mail with our 1K kits are more flexible (more fare choices) but the extra ones you can earn only offer the six fare types in Domestic Econ. Who the heck knows anymore. However, if UA is trying to "simplify" their coupons/upgrades then this is NOT the way to do it. Maybe they just reprinted every piece of paper in the 1-K kits and changed every last thing since I got my kit mid Jan... let me know what the "new" ones say.
