Thought this was a very informative article put out by the NWTF regarding air travel of your firearm,especially with so many of us hunting other states and for BT provinces..Heres the article....
Every year millions of men and women travel to different states or even out of the country to hunt or compete in shooting events. When taking to the air, traveling hunters and shooters must take special care to follow airline regulations regarding transporting their firearms.

For firearms, the rules that applied prior to 9-11 haven' t changed greatly. However, following some key points will make your trip more safe and enjoyable.

Be early - Right now the airlines are telling the average flyer to arrive one to two hours before takeoff. If you are traveling with a firearm, arrive sooner. When checking in you will need to fill out a form declaring the firearm is unloaded. Gate agents will open your gun case to verify this.
Call ahead - Rules concerning firearms can change quickly. Ask for the rules when you book your trip, and call back a few days before you leave to ensure nothing has changed.
Open your mouth - Declare the firearm to the first representative you see. When you declare, call your weapon a firearm, not a gun or weapon. Those words can cause unease, which may mean delays for you.
Be a hard case - Airlines require that firearms be transported in the original manufacturer' s box or in an approved hard case that is lockable. Have the key ready since you will need to unlock and relock it during check-in.
Check the extras - Knives and ammunition must be stored separate from the firearm and packed in checked luggage. Airlines have different regulations on how much ammunition can be carried and most require you to transport it in its original packaging. Any amount above the allotted weight will cost extra. Check with your Airline for specific restrictions.
Know the laws - Before heading out, read up on the gun laws for the area that you are traveling, especially if you plan to leave the country. Countries like Canada and Great Britain require documents months before entering the country with a firearm.
Be responsible - Every time you are out with a firearm you become a representative of the shooting sports. Follow gun safety to the max and prove that responsible gun owners are a danger to no one.
