Lake Manyara, Zanzibar Kisauni, and Seronera are the top three Regional Air airports based on our airline data. This may change if Regional Air makes updates to their flight routes due to supply and demand.
Regional Air does not have flights from Singapore Changi at the moment. There are scheduled flights with Regional Air out of Zanzibar Kisauni though (if you don’t mind flying from this airport). Flying with Air India is recommended if you still want to fly from Singapore Changi.
