My thoughts exactly, particularly if you select an airline that offers a 50% class of service bonus.
Take a routing of say SMF-IAH-CDG-IAH-SMF (13,000 base miles RT, plus a 6,500 class of service bonus in BF), your net loss of mileage is only 3,500 by taking the company's incentive. Then there's that pesky tax burden...
