I'm lost in the air travel debate and it sucks. Ignoring the strike and pilots specific concerns, IMHO:
Emissions of flights are horrendous and will be viewed as barbaric in 30+ years. It needs to stop.
Denying those of a lower income the opportunity to partake in air travel is also horrendous, and should not be the main mechanism to disrupt the industry.
There are, in many cases, no alternatives to air travel, so it cannot be abolished.
Smarter regulation is needed, but the finite details will likely never suit a majority of people.
Actual emissions taxing is basically a necessary step when it comes to air travel - currently, the fuel is completely tax free and that's not great. Take all of that money and pump it directly into rail, which is the actual way forward for intra-continental travel.
It will get more expensive and less accessible for lower income people. There's just really no way around that.
