I was talking to a guy in the past few weeks and he was telling me that some of the major carriers, AA, UA, etc. are going to only allow miles for upgrades if your a premium member as there are so many ways to earn miles now that the upper tier flyers are not able to upgrade.

Has anyone heard that? It makes no difference to me as I'm Exec Plat with AA and get free upgrades and rarely do not get an upgrade.

Just curious!
