Joys of Low Cost flying.
In past years, a percentage of these pax would have caught a Greyhound or thumbed down a passing lorry for a ride. Now, it's cheaper to book a seat on a 737 without the hassel of sitting by the side of the road with all those wordly goods, waiting for a kindly driver to stop and offer a ride. At least with a paid ticket the pax can complain. Wouldn't like their chances bitching about a late arrival because of a lorry drivers sleep requirements.
