Codes Canadian deal hunters should know
Knowing codes speeds up every search, and city codes unlock cheaper combinations. Search YTO to include Toronto Pearson (YYZ), Billy Bishop (YTZ) and sometimes Hamilton (YHM) in one go, or YMQ for Montréal. Border-adjacent travellers should also memorise BUF (Buffalo), BLI (Bellingham), PBG (Plattsburgh) and BTV (Burlington) — they often undercut Canadian airports on US and sun routes.

Frequently asked questions
What is an IATA airport code?
It is the three-letter code assigned by the International Air Transport Association, used on tickets, bag tags and booking sites — for example YYZ for Toronto Pearson.
Why do so many Canadian airport codes start with Y?
Early radio and weather-station codes in Canada used a Y prefix, and the convention carried into airport codes. Most major Canadian airports start with Y.
Can I search a whole city instead of one airport?
Many booking sites accept city codes such as YTO for all Toronto airports and YMQ for Montréal, which helps you compare nearby airports in one search.
