AS has not changed much since September 11.
Meals up and down the coast remain the same. Dinner is still three course and the entree choices are always nice. Lunch has gotten a bit better with one hot sandwich option these days.
Concerning the MD-80 issues, they will be around a bit longer now, because AS defers some a/c deliveries. However, even the Mexican routes are seeing the usage of more Boeing 737s. You will be fine...
Welcome back to AS!
