Third-party recognitions are used only as an input to the calculation; their listings and placings are not republished. See the methodology (IVCA v2.5).
The calculations of each edition and the data-validation processes are carried out with the help of artificial-intelligence agents. The methodology, the weights, the sources and the editorial decisions are Vuelopedia’s.
No assessment of this kind is entirely objective. IVCA results should be read as a methodological approximation for identifying the best performance of airlines, airports, alliances and frequent-flyer programmes, not as an absolute or unchangeable truth. They are also a snapshot in time: the index is recalculated every quarter and changes with events and with the data available.
