Reading SAS’ record
SAS sits in the top fifth of the 94 airlines measured.
The extremes are far apart. On ABZ to CPH it arrived on time 90.83% of the time; on MAN to ARN the figure was 64.51%. Same airline, same fleet, same procedures — which is the clearest argument on this site for checking the route rather than the carrier.
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.
SAS 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 SAS’ 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.
