When flying home becomes cheap enough, leaving for work abroad stops being a permanent break, so fewer people emigrate for good. The same low fares let people from one country buy second homes in the countryside of another, changing how ordinary lives are arranged.
A boss who picks loud fights with airports, staff and rivals and pulls stunts generates an endless stream of news coverage. The controversy itself works as cheap advertising for a company that will not spend on anything else.
A business built on the lowest price has to keep pushing down every cost, so it ends up in open conflict with the airports that charge it fees and with its own pilots over pay and conditions. The constant fights are a direct result of the low-cost model, not an accident alongside it.
