MDW performance data

At MDW (Chicago, IL) in 2020, 9.33% of 60365 departures were cancelled and 7.2% left 15+ min late.

We hold 26 validated statistics for this airport, covering 1989 to 2024.

What this does not meanThis airport’s figures span 1 January 2018, when the DOT changed both which carriers must report (from 1% to half of one percent of domestic scheduled passenger revenue) and how flights are attributed (from the operating carrier to the marketing carrier). Figures either side of that date describe different populations of flights, so they are listed by year below rather than drawn as one continuous trend.

What this page does not tell you

  • Cancellation and delay rates are not directly comparable between airports. Route networks differ and so does the weather they fly through, and the source data says so.
  • Nothing here tells you what you are owed. That depends on the rule that applies to your situation, which is on the passenger rights pages.
  • These are counts and rates, not explanations. We have not tested why any figure moved.

How this article was produced

Produced with AI assistance and reviewed by a named human before publishing. The pipeline that pulls the federal data and computes the statistics is conventional software, not a language model. Software is never credited as an author.

Before a page can publish, an automated check matches every number in the draft against the stored source row. If a digit does not reconcile, the article is blocked. The same check confirms the period is stated, the citation is carried verbatim, the licence permits the use, and no comparative claim outruns its stated uncertainty.
