If flights are carrying that much hydrogen around with them they should also just use them for "free" lift. I don't think hydrogen fuel tanks save the airplane, I think they return us to economic models where the blimp/airship make more sense.

Liquid hydrogen is significantly denser than air.

Right, which is why it "weighs" more and starts to make sense for a flying vehicle to store more of it as gas (less weight, more ballast) and the more you store as gas the closer you get to reinventing airships/blimps/zeppelins.
