> Is it fair that 1 person out of 10 gets to fly while the 9 others will have to pay the same consequences?

This isn't an aviation unique topic. You can replace "fly" in that sentence with countless other activities and the same tradeoff applies as virtually every activity currently involves carbon emissions at some point.

There is a massive difference between an airliner's emissions flying from US to Europe and your local GA pilot cruising to the next town over to get lunch on the weekend though. Does that person need to fly to do that? No, they could drive. But the guy that wants to go cruise around the lake all day on his boat or drive his semi-truck sized RV to go camping for the weekend doesn't need to do either of those activities yet no one here has a moral problem with that.
