Reading Blue Islands’ record
Cancellation is where Blue Islands stands out, and not well: it cancelled 4.04% of its flights against a median of 1.21% across the airlines here — 3.4 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.
Blue Islands sits in the bottom fifth of the 94 airlines measured.
The extremes are far apart. On JER to NCL it arrived on time 72.92% of the time; on BHX to JER the figure was 45.45%. Same airline, same fleet, same procedures — which is the clearest argument on this site for checking the route rather than the carrier.
Blue Islands appears in the record departing from 10 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.
Blue Islands 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 Blue Islands’ 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.
