I'm new to touring but i'm planning on cycling the length of Italy. However i have a question about flying with my bike, I apologies if this has already been asked! Can i simply just put my bike on a plane without a box? As i will be going from one end to the other, carrying a bike box wouldn't be possible, i could pick up a cardboard box to fly out with and then throw it, but what's the best option for getting a bike back? Thanks for your help.
