The only ticketing change that I'm aware of is that AAirpass tickets are now electronic. I'm not an agent, so I don't know if there are any other changer, or whether the fact that the tickets are now electronic makes any significant difference in the ticketing procedure. As an aside, the switch to electronic AAirpass tickets is not a result of the war, it's just coincidental timing. AA announced some time ago that all ticketing would be electronic in the near future, and this just happens to be when they imnplemented that for AAirpass.
