British Airways is the most inexpensive way to fly from Canada to Delhi with tickets to India. Flights leave five to six times a day and there is one flight that has a single connection in London before continuing on to a number of different airports. The least expensive trips are from one large international airport to another, like Montreal to Delhi. Prices for round-trip tickets vary by season and how well in advance you purchase them before the travel date. But you can expect a round-trip flight to cost between $1,700 and $2,200, as of October 2010. This is a significant savings over Air Canada, where most flights to India cost $2,700 to $3,300 round trip. After arrival at one of the major Indian airports, you can travel to other parts of the country are by domestic airline. Inclusive travel arrangements can be made through a travel agent or one of several travel websites.
