I'm not sure how much extra, but I would definitely pay extra to fly on green hydrogen. Probably not a percentage. More like $100-$300 regardless of cost of flight (so maybe 100% extra on a cheap flight and 20% extra on an expensive flight).

As it is right now, greenhouse gas emissions is more a limiting factor on my flying than cost, but at a certain cost, that would invert (and as the cost of flights these days rises, cost is becoming more of a limiting factor).
