You'd probably have to call before hand, but I just wanna know how it would go about.
You can travel with pets, but they keep them in kennels in the cargo hold. I think the trip would be far too stressful for your hedgehog ... it's best to leave him home or with someone who can care for him while you're gone.
Probably if you puthim in a animal carrier, but if you want to make sure. You should call and ask if you can and how much it would cost so your ready for all possibilities
