Source-derived summary

The following is a list of defunct airlines of the United States. However, some of these airlines have ceased operations completely, changed identities and/or FAA certificates and are still operating under a different name (e.g. America West Airlines changed to use the identity of US Airways in 2005 – which itself also changed identity to American Airlines in 2015).

Editorial analysis

Why this record matters

The phrase “wikimedia list article” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q96389305. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2005 and 2015.

Critical limits

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
