Now that most merger issues have been tackled, expect to see AA finally swapping metal around to right-size routes. Hopefully we don't see type-locking at hubs, or the A320, E190, and A330 may not come here. The A330 is a natural fit for plenty of routes, especially DFW-South America. Having a CLT/PHL-DFW positioning flight would be icing on the cake.
Don't read anything into the ramp markings, that's just preparedness. If you look at what is already out there it can be sometimes shocking.
