If you restrict yourself to the part of the world that can actually afford to fly, aviation looks quite a bit worse. Taking a trip from Europe to California is a good way to basically double my carbon footprint for the year.
Aviation is also fairly unique in that we don't know how to make it climate neutral. Even burning synfuel made from renewables won't be enough, because adding emissions higher in the atmosphere has a stronger warming effect. And we just don't know how to make all-electric long distance planes yet.

It has a temporary strong effect, that falls back into the normal one in a couple of decades. What means that synfuel based aviation would have a constant impact on the global temperature, like painting your ceiling black. We can live quite well with that.
