Airfreight from Sudan to Chad?
 

in planning a little 3-man motorcyle jaunt from Cape Town to Dakar, I'm looking for alternatives to the preferred route of riding from Khartoum to N'Djamena as I doubt Darfur will be an option.
I'm looking for info on airfreight from Khartoum to Chad. has anyone else done this? mercifully, our bikes don't have batteries so that's one less hassle!
thanks in keen anticipation
