Reading Aer Lingus’ record

The extremes are far apart. On BRS to DUB it arrived on time 90.51% of the time; on MAN to DUB the figure was 60.73%. Same airline, same fleet, same procedures — which is the clearest argument on this site for checking the route rather than the carrier.

Aer Lingus sits mid-table, which for an airline's punctuality is a better outcome than it sounds.

Aer Lingus appears in the record departing from 8 countrys. Because each regulator publishes on its own terms, a figure spanning several of them is an average over several definitions — close enough to compare, but the country pages are the more exact reading.

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.

Aer Lingus 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 Aer Lingus’ 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.
