I get that you may have to see family abroad or maybe indulge for a holiday, but this is "I'm using an airplane to commute" kind of level.
And here I am trying to book my train tickets to go to London instead of flying even though it costs three times as much just to avoid a few kg of CO2 (among other things), it's making me angry.
On the price, the very annoying thing is that fuel for planes is not taxed! Changing this would require quite some effort (falls under some specific laws, that are old and nobody wants to touch, etc.) but I think everybody should just ask "honest tax on fuels!" as this will make less people say (or thin) "but climate change is a hoax". Planes are just unfair competition to other transport due to taxes!
An alternate approach that would be seen as consumer and business-friendly would be subsidizing companies with a certain level of fuel efficiency per passenger mile, targeted above current levels.
Reminds me of the soggy straw memes floating around now. I've been having those why bother? thoughts as well.
