There was uncertainty about the total climate impact of flying, with IPCC cautiously estimating it at double the impact of the CO2 emissions alone.
The EU now concludes its probably more like three times the CO2 impact.

So if you'd consider a CO2 price for aviation, better make it 3 times as high as for other emitters, to reflect total climate damage done. Same for personal carbon footprints, by the way.
On the solutions side, this underlines the importance of reducing the non-CO2 climate impact of flying as well, e.g. when developing zero-CO2-emission jet fuels. The report (link in article) discusses that as well.
On aviation's share in causing climate change:
It causes 2.4% of CO2 emissions (the number you'll mostly see)
That's 1.7% of all greenhouse gas emissions.
But including indirect warming effects, aviation already causes 5% of climate damage.
