To be sure, I am grateful that Benito et al are willing to allow mileage plan credit for flights taken using mileage plan miles. Excellent. Given the substantial amounts of redeemable miles required to purchase seats in first class, which can be 3-4 times the required miles needed for an economy class award, my query is; will the use of such miles for a ticket in F class, which generally results in a 50% bonus in eqm, convert to an equivalent amount of eqm miles (150% of the flight miles flown) to the mileage plan user's account for using his/her miles for the award taken for the trip?

Hope so. I'm about to book F flights SFO-JFK, my favorite route. After checking the flight options, the number of miles needed to go to the F cabin, over the economy cabin, is in the range of 3.2 - 3.75 times the economy requirement. Checked a number of times and route options. So, before I book, I'd be glad to know if AS will be awarding eqm with the 50% bonus on credit for first class travel, in the new mileage plan reward system. Again, hope they do, but if they don't it will affect how I book and fly.
