in the "good" old days when AA would issue certs for domestic upgrades.. with more flights then today,
with me starting my life with AA.. I able to upgrade quite a few of my flights.. DFW- LAX. ORD -LAX etc
would always count out the mileage to make sure I got max use of my 500miles certs
today.. even with my status.. upgrades are now more of a blue moon then the norm
