Mazar-I-Sharif, Kabul Khwaja Rawash, and Herat are the top three Ariana airports based on our airline data. This may change if Ariana makes updates to their flight routes due to supply and demand.
Ariana does not have flights from Singapore Changi at the moment. There are scheduled flights with Ariana out of Islamabad Intl though (if you don’t mind flying from this airport). Flying with JetBlue is recommended if you still want to fly from Singapore Changi.
