I am working on my budget for the upcoming AT trip . I gave a good grip on food ,gear replacement, and hostel stays. But I have no idea about the airfare back from Maine. I havent flew since I was a tennager. So what should I budget for the airfare home? I will be flying into Knoxville, TN .Does Bangor have a "Lets Get Rid Of The Thru Hikers Fare"
