Quoting FFlyer (Reply 3): Isn't that the same things as with somebody mistakingly depositing money on your bank account; you can't keep the money, they will take it back, or actually you have to return it?
Well i think money is somewhat different, since it is actually legal tender. I'm guessing the government can actually arrest you or something if you don't return money, since the bank might claim theft or something. Airlines miles, AFIK, have no cash value and are only regulated by the contract that you agree to with the airline in accruing/redeeming them. Sure, the airline can take them away, but if you don't tell anyone they'll probably never know/care.

Quoting MarcoPoloWorld (Reply 7): What if you pay Y fare and redeem miles to upgrade to J ? Will you still accrue miles?
In the 1990's I upgraded a Delta deeply discounted economy fare to first class using frequent flyer miles. That was back in the day when Delta was giving a minimum of 1,000 per leg with 2x bonus for first class. The itinerary was MEM-DFW-SLC-GEG, and I received the miles (1,000 minimum per leg at that time) + 2x mileage for first class travel.
If memory serves me correctly, I earned more miles on that trip than it had taken to upgrade from the discounted Y ticket to first.
