Arik used to fly Abuja-Ibadan route. They fly straight to Ibadan with Ilorin-bound passengers on board, pick up Ibadan- Abuja passengers, stop at ilorin for passengers to disembark and pick up Ilorin-Abuja passengers. That means the flight is Abuja- Ibadan but with stop over at ilorin on the return flight.
I don't know what you mean by political or business purpose but people in Ibadan and surrounding areas dont have to go to lagos to catch a flight or fly from Abuja to lagos then travel by road or eail to Ibadan.

Thanks alot, with the current security situation, i have been searching for flight from

Port harcourt - ibadan but couldnt get any.
