Grab my always packed camping pack and rifle case + ammunition, get in car, drive to airport, call 911 on the way and inform them that armed individuals are breaking into my house providing the address and hang up immediately, park car at airport parking lot and pay with card, take taxi back into city with cash, get bus ticket with cash which takes me out to the woods/mountains, camp there until I can’t.
It would also be wise to immediately book a one way ticket to anywhere on the way to the airport and then not use it.
Even if they have access to my payment details, the last things they would see are parking for the airport and buying a plane ticket.
They would need access to the airports CCTV to determine that I did not actually board the flight.
If they had access to this, and were able to get access to the city CCTV as well, the best they could possibly determine after many hours or days is that I was last seen taking a bus west.
