The notion that wildfire smoke is ‘natural,’ and therefore less harmful than other types of air pollution, is not supported by the evidence. Wildfire smoke has been linked to adverse health effects.
All up, your risk of catching COVID on a flight is very low. But there are things you can do to lower that risk even further.

3D printers got a lot of attention when DIYers leapt to action to address equipment shortages early in the pandemic, but some everyday items found in hardware stores played a big role, too.
The NSW and Victorian government say they’re providing schools with adequate options for ventilation, including air filters. But schools can’t take proper action without monitoring air quality.
Low-cost air-ventilation systems have been installed in many classrooms across the U.S. to help reduce COVID-19 transmission.

Air-ventilation upgrades have been badly needed in U.S. classrooms since long before the pandemic. Low-tech filtration systems that cost about the same as a textbook per student can make a big difference.
