I had cause to look up the baggage policies at Air-Tran airways, and I noted their view of military personnel. I thought I should note same here....
"Active military personnel
We make an exception to our checked baggage allowance policy for members of the military who are traveling on active duty orders. As long as each piece of baggage does not exceed 100 pounds in weight and 80 inches in size (length + width + height), baggage will be exempt from AirTran's baggage limit, and will NOT be subject to excess, oversized, or overweight baggage charges."
Nice. Delta could learn from Air-Tran.
