Do you need ushahidi to prove that JKIA is busier than JNIA, MIA is busier than Abeid Karume and Eldoret is busier than Kilimanjaro? You guys are a special case indeed.
Simple mathematics appears not simple in Tanzania. Your airline industry is where Kenya was in 1990.
Moi International Mombasa passenger numbers (2013) - 1,313,168
Kilimanjaro Airport passenger numbers (2015) - 780,800
There is no point even comparing JKIA and JNIA.
For JNIA to come close, you will have to add together all airports in Tanzania, plus all airports in Uganda.
