I'm pretty sure getting extradited is a "special event" :-)

I would assume they charge you for extradition as part of your court fees. Similarly to my knowledge if you get deported or have to leave a country for visa reasons you have to pay for your own travel even though the date of departure is enforced by customs and/or law enforcement. Though fortunately I have never been extradited and I hope to keep it that way.

Afghanistan to Gitmo is quite a long way.
