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 summary

This brief starts where responsible research should: with the source description of “List of defunct airlines of the United States (D–I)” as wikimedia list article. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical starting point whose main value is the path it opens into stronger specialist and primary sources. The current lead gives the account dated anchors—2005, 2015—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where List, defunct and airlines can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as wikimedia list article. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q104837791. 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.
