Booking Strategy
For Delhi to Kathmandu, the sweet spot is booking 4-6 weeks ahead for direct flights. Prices drop significantly during monsoon (June-August) when tourist traffic is low – you can find direct flights for as low as €150. October and November are peak trekking season, so book 8+ weeks ahead and expect to pay €400+. Tuesday and Wednesday departures are typically €20-40 cheaper than weekend flights. Use Google Flights to track prices, but book directly with Air India or Nepal Airlines for the best counter-deals. If your dates are flexible, shifting to mid-week flights in July can save you over 50% compared to October weekends. Avoid booking through third-party aggregators for this short route – airlines often have lower fares on their own sites.
Route Tips
- Use the prepaid taxi counter at Delhi Airport Terminal 3 (International arrivals) – fixed rates to city center prevent haggling and overcharging.
- Indian citizens don’t need a visa for Nepal – simply carry a valid photo ID (Aadhaar card or passport) and can stay up to 150 days.
- Delhi Airport Terminal 3 handles all international departures including Kathmandu flights – check your airline Terminal 3 specific check-in counters.
- If traveling during Dasain (October) or Tihar (November), book flights 6+ weeks early as Nepal residents traveling home spike demand significantly.
- Consider a morning flight (6-9am) for the best chance of clear Himalayan views – afternoon flights often encounter cloud cover over the mountains.
