Reading SkyWest Airlines’ record
The extremes are far apart. On BOI to LAX it arrived on time 98.41% of the time; on SAN to SFO the figure was 32.54%. Same airline, same fleet, same procedures — which is the clearest argument on this site for checking the route rather than the carrier.
SkyWest Airlines’ record swings sharply from route to route — roughly 12 points either side of its own average. An overall figure hiding that much variation is not much use on its own: the route you are flying matters more than the airline's headline number, and this is a carrier whose average is being held up by some routes and dragged down by others.
More of its delay is self-inflicted than not: about 66% came from causes inside the airline rather than from weather or airspace.
SkyWest Airlines 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.
SkyWest Airlines 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 SkyWest Airlines'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.
