Flight changed everything when it comes to warfare. But as far as individuals are concerned, the average human on the planet will take a handful of flights in their lifetime, at best, and nearly all flights that are taken are for recreation which is ultimately fungible with other forms of recreation that don't involve taking flights, and of the flights that aren't for recreation most could be replaced by things like video calls, and the vast and overwhelming majority of the goods that make up the lifeblood of the global economy are still shipped by ship, not shipped by air.

Which is to say, the commercial aviation industry could permanently collapse tomorrow and it would have only a marginal impact on most people's lives, who would just replace planes with train, car, or boat travel. The lesson here is that even if normal people experience some tangential beneficial effects from LLMs, their most enduring legacy will likely be to entrench authority and cement the existing power structures.
