That I agree and that's why I had not used Amex for my plane tix much.
Not to plant ideas in Amex's head, but one way to increase spending and decrease crowding is to require use of Amex card to purchase (or pay taxes on award tix) the plane ticket to access the Centurion Lounge. That would be way more effective than the 3 hour limit or no access arrival.
