This is out of the NRA's American Hunter Mag.
"The Pennsylvania based airlines USA 3000 has banned all transportation of firearms and ammunition in passengers baggage, both carry on and checked. This means you can't use this airlines when traveling to shoots or hunts if you intend to bring a firearm. USA 3000 executives made their own discretion, even though no other major airlines in America has chosen to trample on the rights of law-abiding Americans. At press time, Trevor Sadler, Director of Sales and Contracts of USA 3000, had not responded to numerous requests for an interview. There are nearly 1 million deer hunters in the airlines home state of Pennsylvania. Hunters and shooters are tourists too. So inevitably the loss of business from the NRA's nearly 4 million members will have a financial impact on USA 3000. Currently, other airlines in the United States have Transportation Security Agency (TSA) approved policies that allow hunters and shooters to check firearms."
