...but what is an LCC today?
I've recently flown on Southwest and apart from the 'choose your own seat' thing, it's better than the legacy airlines.
Legacies charge extra for food, charge for all checked luggage, while Southwest lets me check two bags for free and gives me free peanuts and softdrink -and 2nds if I want. What was once 'cheap and nasty' is now pretty good, all because the others plumbed new lows in service.
