Because the two cities are separated by an immense global distance of roughly 12,400 kilometers, all itineraries departing from Tribhuvan International Airport (KTM) require at least one or two stopovers at major global aviation hubs.
The most reliable carriers serving this route are Qatar Airways (via Doha), Emirates (via Dubai), and Turkish Airlines (via Istanbul), usually connecting through major U.S. gateways like Chicago (ORD) or Houston (IAH).
