I'd still feel more secure flying than taking a car trip that required an overnight stay at a hotel.

The air in the cabin isn’t sealed in. Fresh air is continuously introduced during the flight. A plane’s jets are already sucking in and compressing huge volumes of air to burn with the aviation fuel. Some of this is diverted for the passengers to breathe. Because the compression heats up the air, it must first be ducted around the wings to be cooled down. The air already in the cabin is passed through high-efficiency particulate (HEPA) filters to remove bacteria and viruses and then mixed 50:50 with the fresh air from outside. The excess cabin air is vented through valves to the rear of the plane to keep the cabin pressure constant.
This system means that the air in the plane’s cabin is completely replaced around 15 times an hour, but this is mainly about controlling the temperature and removing contaminants. The oxygen that all the passengers breathe is less than one percent of the fresh oxygen entering the cabin.

Many believe that aircraft cabin air is constantly recycled, but it is actually completely flushed through the system every 3-4 minutes being replaced with fresh air from outside the aircraft.

Aircraft are not sealed tubes, look at the tail of any passenger plane and you will see a hole, it can be several feet across. That is where the air comes out. If you stopped an aircraft from moving and shut down the engines, it would quickly depressurize (not violently). The dynamic is like a water sprinkler - more water comes in from the hose than can go out of the sprinkler. That increases the internal pressure. Same thing with a plane - the engines route more air into the cabin than can escape at the same rate. The difference causes the cabin to pressurize.

The Ask the Pilot article would seem to somewhat contradict that at least in all but Airbus' craft. Unless I read it wrong, Pilot claims that while oxygen levels are controllable air replacement rates are not.
