The route in brief

Kathmandu → Bangkok is the default gateway from Nepal into Southeast Asia. Most onward flights to Phnom Penh, Ho Chi Minh City, Bali, or Kuala Lumpur connect through Bangkok's Suvarnabhumi (BKK) or Don Mueang (DMK). The direct-flight market is competitive enough to keep prices sensible.

Thai Airways — full-service, premium. Widebody equipment (A330 or similar). Baggage generous, meals included, in-flight entertainment. Most expensive but most reliable.
Himalaya Airlines — Nepal-based carrier serving the route. Mid-tier service, competitive pricing. Narrow-body A320neo.
Nepal Airlines — flag carrier, flies KTM–BKK several times weekly depending on season. Full-service, mid price.

Booking tips

Compare Thai Airways direct, Himalaya direct, and Yatra — the cheapest is not consistent across sites.
Avoid December 20 – January 5 and April 10–17 (Songkran): prices double.
If flying onward to Bali/Phnom Penh, search round-trip KTM–final-destination via Bangkok on Kayak or Skyscanner; sometimes a through-ticket is cheaper than separate legs.
