I have learned something new from the airlines when the family and I went on emergency leave. We were told that if you are military and are on orders (including being on leave) you are allowed three FREE checked bags weighing up to 70 pounds. This only applies to the Servicemember; so the nice lady at the check in table told us to put all three of bags under my hubby's name. Overall, we saved $125 from this discount.
**We were told that this is for all airlines but I would recommend checking with your airline prior to flying.**
