Kathmandu (KTM) → Doha (DOH)
A reference for the Tribhuvan International Airport to Hamad International Airport route. You'll find the operators on file, the great-circle geometry, the connecting options if no nonstop fits your dates, and a short profile of each endpoint airport.
The flight from Kathmandu (KTM) to Doha (DOH) covers a great-circle distance of roughly 3,360 km (2,088 miles). Aircraft leave Tribhuvan International Airport on an initial west heading. As international sectors go, this one sits in the long-haul bracket: long enough that most carriers run it as its own dedicated rotation, but short enough to fit inside a single crew duty period.
2 carriers file a direct KTM to DOH sector, with Qatar Airways and Royal Nepal Airlines among the operators on record. A route attracting this many carriers usually points to a city pair with both leisure and business demand, or a competitive hub-to-hub link where the airline alliances overlap on the same metal.
Operators on the KTM → DOH direction
Carriers with at least one scheduled rotation on this sector in the OpenFlights dataset, ranked by the number of code-shared filings.
This is a long-haul sector. It's long enough that the heaviest rotations need wide-body aircraft, but short enough that twin-aisle types like the Airbus A330 and Boeing 787 carry the bulk of the traffic ahead of the larger 777 and A350. Plan for an in-flight meal service, an entertainment cycle, and a block time near 4h 41m.
If a nonstop doesn't match your dates, Singapore (SIN), Seoul (ICN), and Istanbul (IST) show up on both ends of the network and make the most natural connecting points. The connecting-hubs grid below extends that list to the eight strongest options, ranked by each airport's overall departure activity. That ranking is a fast proxy for how many onward flights a single stop is likely to feed.

This is an international sector between Nepal and Qatar. Build in time for passport validity, possible visa requirements, and the time-zone gap between Kathmandu and Doha. International itineraries are quoted in local time at each end, so a "midnight" departure in Kathmandu typically lands the next morning in Doha. Customs clearance happens on first arrival in the destination country.
On the day of operation, the KTM to DOH direction lifts off heading west, then the great-circle track curves to compensate for the Earth's rotation. The return DOH to KTM sector heads east out of the gate, with 2 operators on file for the inbound side. Combine the two operator lists for a full picture of the city pair's competitive landscape.

Reading this route page
The operator list reflects scheduled-route filings in the OpenFlights dataset, not real-time availability. A carrier appearing here publishes a scheduled service on this sector. It isn't a live timetable, and the actual flight numbers, frequencies, and aircraft types shift season to season. For booking and current schedules, cross-reference the airline page above with the carrier's own website.
Distance here is the great-circle arc between the two airports' published coordinates. Real flight tracks wander off that line because of wind, ATC routings, oceanic crossings, and political airspace constraints. Block time is an estimate covering ground taxi, climb, cruise at typical jet speeds, and descent. Real block times shift with aircraft type, weather, and traffic, so treat the stat-strip number as a planning indicator rather than a published flight time.
