Obviously you cannot carry guns or ammunition onto a commercial jet. They will have to be put in your checked luggage. Don't try to bluff it and say it is OK because you are military. The airline officials will not be impressed and may not allow you on the plane at all. Each airline has its own rules concerning the checking of firearms and they are quite specific so once you have your ticket you should call and ask what those rules are. The rules for all airlines will have to comply with the Transportation Security Administration rules for transporting firearms. We will not try to summarize them here because they are constantly changing based on the perceived threat.
