Since Canada is such a vast country, sometimes the only way to get from one place to another in hours instead of days is to fly. Canada has one national airline, Air Canada and several regional airlines.
Canada has three main international airports:
There are other international airports across the country, but the majority of these only serve flights going to or coming from the mainland United States.
We also have several discount airlines, but you shouldn't worry that discount will mean unsafe. Airline safety standards are regulated by Transport Canada. The flights on discount airlines are cheaper because of fewer flights and less in-flight perks such as free drinks and meals. It is well worth the sacrifice to save your money by flying discount.
