>>Yesterday, my father-in-law bought a round trip ticket with his miles for my sister-in-law to fly from ORD>SFO over the same dates (fewer miles round trip). They charged him 42,000 MILES!<<
Ahh yes - forgot about that. Often there is a different price if it is YOU travelling rather than someone else - Why? Because someone at Delta saw that they could make more money doing it this way. They are your miles. You earned them. Why do they need two prices?
