Cheapest International Flights from India

Nepal (Kathmandu) is the cheapest international destination by flight from India — fares can start as low as ₹3,999 from Delhi or Varanasi. Sri Lanka, Bhutan, and Bangladesh are also very affordable. For Southeast Asia, Thailand and Malaysia offer the best value.

Chennai, Kochi, and Kolkata tend to have cheaper international fares because of proximity to Southeast Asian and Middle Eastern hubs and lower airport charges. Mumbai and Delhi have the most route options. For Dubai, almost all major Indian cities have competitive fares. For Southeast Asia, fly from Chennai, Kolkata, or Bangalore for the cheapest rates.
