Almost all airlines use a GDS system and if you happen to live in California then under the California Consumer Privacy Act (CCPA) you have the right to know what data they store about you from the last twelve months. Three GDSes that matter are Amadeus, Sabre and Travelport (which includes Apollo, Galileo and Worldspan but since we will be dealing with companies this doesn't matter). I know this is not what you asked but this is AFAIK the best you can do currently.
