Frequently asked questions

What is the IATA code for Kathmandu airport?
Kathmandu's airport uses the IATA code KTM, short for the city itself. Tribhuvan International is the only commercial airport serving the capital and the entire Kathmandu Valley. Always search KTM on Flightmussy rather than a generic country search to get the cleanest fare set for the Himalayan gateway.
Which low-cost carriers serve KTM?
IndiGo dominates LCC traffic from India, with AirAsia connecting Kuala Lumpur, FlyDubai linking the UAE and Jazeera Airways serving Kuwait. These carriers often undercut full-service fares but get buried in default search results. Flightmussy surfaces them prominently because Google Flights frequently de-prioritises low-cost options.
When should I book flights to Kathmandu?
For the autumn trekking peak (October-November) book three to four months out, as Everest base-camp season fills early. Spring (March-May) is the second peak. Monsoon months June through August are cheapest but flying into Lukla is unreliable. The free 12-month fare heatmap on Flightmussy makes the pattern visible instantly.
Are there direct flights from KTM to London?
There are no direct scheduled flights between Kathmandu and London at present. Practical one-stop routings go via Doha on Qatar Airways, Dubai on Emirates or FlyDubai, or Delhi on Air India and IndiGo. Flightmussy compares one-stop options on a single page and is free, with no signup required.
