Reading Air Canada’s record
Cancellation is where Air Canada stands out, and not well: it cancelled 2.73% of its flights against a median of 1.21% across the airlines here — 2.3 times the typical rate. Cancellation is also the outcome that costs a traveller a day rather than an hour, and the one that triggers a refund entitlement where delay does not.
Air Canada sits mid-table, which for an airline's punctuality is a better outcome than it sounds.
Each axis is a percentile against the other US airlines in the same period, not an absolute score. Further out is better than most; nearer the centre is worse than most.
Air Canada in five measures
An airline's headline on-time rate hides more than it shows. Two carriers can both arrive on time 75% of the time while one is late by twelve minutes and the other by an hour, or while one is evenly mediocre everywhere and the other is excellent on most routes and dreadful on a few.
These five axes pull those apart. Each is scored against the other US airlines in the same period rather than on an absolute scale, because on-time rates cluster tightly enough that raw numbers would draw every carrier as the same shape.
Same everywhere is the one worth reading twice: it measures how far Air Canada’s on-time rate moves from route to route. A carrier scoring low there has an average propped up by routes you may not be flying.
