List of defunct airlines of the United States (A–C)

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).

For reasons of size, this article is broken into four parts:

• List of defunct airlines of the United States (A–C)
• List of defunct airlines of the United States (D–I)
• List of defunct airlines of the United States (J–P)
• List of defunct airlines of the United States (Q–Z)
