I live in Southwestern Ohio and get probably 75% of my power from coal. My pot of coffee emits far more CO2 than someone in Portland, who gets 0% from coal and most of their power from hydro. It's the same pot of coffee. Our cost of energy is similar and our standard of living is similar.
Where you get your power greatly affects how much CO2 you emit doing the exact same things. All energy is not created equal.
There are two huge barriers to doing anything about this problem. The first is denialists and those with vested interests in fossil fuels promoting denialism. The second is well-intentioned people who understand that there is a problem over-complicating the issue, promoting misunderstandings, or promoting the idea that this can't be solved without massive decreases in standard of living.
The latter, which I term "abstinence based environmentalism" by analogy with abstinence-based sex ed, will work about as well as politely telling teenagers not to have sex. If you tell people they need to become poorer to save the planet, they'll ignore you... especially if they are already poorer than you in which case you look like a hypocrite.
This problem is actually pretty simple. The following steps won't solve it 100% but they'll go pretty far.
(1) Phase out coal for electricity generation in favor of... almost anything else except maybe oil shale.
(2) Push electric vehicles, not because all EVs categorically emit less carbon than gasoline cars but because it's a hell of a lot easier to replace a few point source power plants than it is to replace a vast fleet of millions of internal combustion engines. (That and your typical EV is indeed better... even if your electricity is 100% coal an EV is generally no worse than an ICE car due to the superior efficiency of large power plants and the high embodied energy of gasoline.)
(3) Continue to subsidize renewable energy and grid-scale storage.
(4) At least stop shutting down perfectly good nuclear power plants before renewables are in place to replace them, and at best put some serious funding behind next-generation nuclear efforts. Fusion is also grossly under-funded. Ignore the "it'll always be N years away" idiots. There has been substantial progress even with very limited funding available.
There is no point in quibbling about small contributors like aviation (<5%) while we are still burning shitloads of coal and coal is far easier to replace than jet fuel. You don't solve a problem like this by making the solution maximally inconvenient.
I'm aware of this. I'm living in a place where power is over 99% renewable and makes use of no gas for utilities, work from home and drive fewer than 5,000km/y as a household, and eat a low-meat diet.
The biggest gains to be had are obviously systemic, and what I do as a consumer is far more limited in its scope and impact. I still limit my flights, no longer attend in-person conferences, try to travel more local, because what else am I going to do? I'm aware this is like putting out a cigarette when the whole town's already on fire, but I can't deal with the dissonance otherwise. It's still an individual luxury that can have an oversized impact compared to everything else I do.
Advocating for it is not going to be sufficient at all, but it's still the most impact I can have when all the big stakeholders who have to fix their powergrid are not even in countries I live in.
The unit of capital allocation in airlines is one plane, and cancelling a flight or adding a new one probably requires some advance notice to airports and other agencies not to mention time for maintenance, flight crews, etc. to ready it or take it out of operation. Then there's pilots' unions etc.
So no, your decision does not immediately affect the number of planes flying, but if many people fly less the net effect will be fewer planes in the air after some time delay.
