Other posters already mentioned the storage factor, so I'll mention the safety factor:

Hydrogen is flammable, but kerosene is not; kerosene is instead combustible. Here's the technical difference between the two[0], but in practical terms it means that you can drop a lit match or cigarette into a tank of kerosene and nothing will happen. You can even heat a tank of kerosene directly with a propane torch without igniting it[1].

Hydrogen leaks out of literally any container it's stored in, if you fill up a pure lead bottle(a 25kg bottle only holds 1 litre of hydrogen) it will be empty after 2-3 weeks of doing absolutely nothing - hydrogen molecules are so small they just permeate through any safe to handle material. Obviously planes couldn't use tanks made out of lead because of weight, so whatever material they used would leak even faster - and as hydrogen forms an explosive mixture with air, that's not a good thing.

Liquid hydrogen is really, really, bad as a fuel.

The energy density per mass is very high, but it's also the least dense gas, so the volumetric energy density is absolute crap, even at high pressure. A bucket of kerosene contains a lot more hydrogen atoms than a bucket of liquid hydrogen, and unlike the hydrogen, it's safe to keep at room temperature, at normal pressure, and it's neither corrosive, flammable, or explosive.

Hydrogen is gaseous at normal temperatures. Both Kerosene and hydrogen are flammable, but being gaseous means that the resulting exothermic reaction will happen much faster and thus the energy will be released much more violently (think:explosion).

Additionally, as you said, storing hydrogen densely enough means pressured containers, or extreme cooling (like for rockets).
