AeroDue Intelligence · Historical reliability

Why should reliability comparisons use the same time window?

Using different periods can create a misleading comparison because traffic, schedules and operating conditions change. Match the observation window and metric definition before comparing two samples.

Why should reliability comparisons use the same time window?

Using different periods can create a misleading comparison because traffic, schedules and operating conditions change. Match the observation window and metric definition before comparing two samples.

What to look at

The useful evidence depends on the question. For this scenario, focus on:

01

Same date range

Use the source-backed value as context. If it is missing or ambiguous, AeroDue does not replace it with an estimate.

02

Same metric definition

Use the source-backed value as context. If it is missing or ambiguous, AeroDue does not replace it with an estimate.

03

Comparable sample size

Use the source-backed value as context. If it is missing or ambiguous, AeroDue does not replace it with an estimate.

What AeroDue can check

  • Historical aggregation only when a source policy permits storage and publication
  • Airline, airport or route scope kept explicit
  • No prediction presented when publishable history is unavailable

The guide explains the decision boundary; the linked AeroDue tool provides the current source-backed context available for your journey.

Source and evidence boundary

Historical reliability is descriptive history, not a guarantee or prediction of a future flight. AeroDue suppresses publication when source rights or data quality do not support it.

Updated 2026-10-07. AeroDue does not manufacture missing operational facts, availability, probability, severity or legal eligibility.

What does historical flight reliability mean?

Historical reliability summarizes past operational records within a defined scope. It can provide context, but it cannot tell you with certainty what will happen to a future flight.

How can I check airport health before a flight?

Use the airport's ICAO code in AeroDue Intelligence. The result combines the connected weather and disruption evidence while clearly separating airport-specific signals from broader country context.

These links help with travel planning or evidence gathering. They are separate from any disruption forecast or passenger-rights decision; bookings and terms stay with the provider.
