I mean, it's generally offensive, not necessarily to you or me, just to people. And I suppose we have to bear the relatively recently discovered warming effect of contrails, but in terms of carbon emissions, ourworldindata assigns aviation as a whole only a very thin slice of the emissions pie. But you're apparently talking about, what, PAHs that might give somebody cancer? Not a big deal proportionately, I think, unless you work at an airport.
