List of defunct airlines of the United States (Q–Z)

The following is a list of defunct airlines of the United States. However, some of these airlines have 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:
