Frequent flyer miles for award travel are not worth anywhere close to 2 cents for the airline. Passengers value them at around 2 cents because that's what it would cost to buy a ticket.
For the airline, they only need to accrue a liability equal to the marginal cost of transportation, which is on the order of $20 or so for 25,000 FF miles, or about 0.1 cents a FF mile. For MDT-SNA on UA metal, the 4,600 US miles costs US about five bucks. The five bucks is worth the codeshare in other respects.
