As far a the LCC's go, if you travel with scum you can expect to be treated like scum.
How unpleasant and not true. Plenty of legacy airlines experience disruption in flight, and often from those 'entitled' homo sapiens in the pointy end. If you treat people as you yourself would like to be treated life is often much nicer than popular opinion might suggest. I am definitely not 'scum' as you kindly refer to people who use LCCs, and have never been treated as such by cabin crew, ground handling staff or by their call centres when I have found these companies' routes and prices to my advantage .
