How do you figure? It wasn't going to be burned before. Now it is.
The sustainable way to make jet fuel would be some kind of renewable-powered carbon sequestration - for example, the process described in the paper, but fed with biomass. Burning old plastic is just fossil fuel with extra steps - looked at another way, it's a way to make fossil fuel cheaper by making it earn money as plastic before it gets burned. It's not a win.

Unless we are burning it in a second load of planes built specially for the occaision, it will replace the jet fuel from virgin crude that was going to be used for those trips. I agree that it would be better to feed it with recent biomass, though I would note that this process would also presumably work with plastic made from recent, rather than fossil biomass and we may find that making some single use plastic, (sometimes having a single use wrapper is important), from biomass and then jet-fueling it at the end, might not be a bad way to go, at least until we have developed really good power storage in other ways.
