Precision Air flies to Dar es Salaam, Kilimanjaro, Bukoba and, internationally, to Nairobi. Auric Air has flights to Bukoba, Kigoma and Mpanda. Air Tanzania flies to Dar es Salaam five days a week. Fastjet also flies to Dar.
Coastal Aviation has a daily flight to Arusha airport stopping at various Serengeti National Park airfields. It also flies to Dar es Salaam, Zanzibar and, internationally, to Kigali. Flight schedules and destinations constantly change so it pays to check each airline's website for the latest.
Auric and Coastal both do charters.
