Flat Spin,
Perhaps your brain is in one most of the time. That is a rather high-handed opinion, if you don't mind me saying. There are 1000's of people who now travel, who could not afford it before. That may or may not be a good thing. ATC congestion is contibuted to by the rapid rise in a/c numbers; faster than the infrastructure can adapt, but that's another topic to be debated later.
However, there are some wonderful areas in Europe, which is going to expand shortly with even more beautiful places to visit, where the providers of "proper services" do not wish to fly to, and couldn't make a profit if they did. These little bolt holes, away from the hussle & bustle of big rush rush cities, are havens of peace and tranquility. LCC's are the only way in or out of them, so long may they thrive.
Sadly, though, they are responsible for importing that terrible English disease called house inflation. There are parts of France and other countries where the local economy has been helped by the visitors, on the one hand, and been badly hit by ludicrous house prices being out of reach of the next local generation, on the other. The holiday home syndrome hit places in UK like The Lake District and Cornwall, & Wales just as badly. That was caused by the dreaded Motorway. If the car and red flag still existed, or the only way into the national parks was by slow trains, then this would have been prevented. Sadly, the future marched stalwartly towards us and Canute perished.
