Determining the most inexpensive airline for travel from India to Canada can depend on various factors, including the time of year, availability, and specific departure and arrival cities. However, some airlines that are known for offering competitive fares on this route include Air India, Air Canada, WestJet, and Qatar Airways.

To find the most cost-effective option for your travel dates, it’s recommended to compare prices across multiple airlines and utilize flight search engines and travel websites. Some popular platforms you can use for comparing flight prices include Skyscanner, Kayak, Google Flights, and Expedia. These platforms allow you to enter your travel details and search for the best available fares from various airlines.

Additionally, it’s worth considering the flexibility of your travel dates, as flights on weekdays or during off-peak seasons tend to be more affordable compared to peak travel times. Keep an eye out for promotional offers, discounted fares, and any ongoing airline sales, as they can provide additional savings.

Remember to carefully review the fare conditions, baggage allowances, and any additional fees that may be associated with the flights before making your final decision.
