Also, redeeming your miles is MUCH easier on UA than Miles&More (M&M is the joint frequent flier program of all of Lufthansa group airlines and a few others). It starts with the fact that you'll even be unable to look up redemption rates on Miles&More until you have 7000 miles in your account Also, Miles&More charges surcharges ALWAYS, while on MileagePlus you can get premium redemption tickets with significantly lower cash payment in taxes and surcharges. Although Dynamic Pricing makes it a bit worse of a deal, but it's only a matter of time until Miles&More moves to dynamic pricing too...
