Spain/Canaries are by far the worst in my experience
Many a year ago I was airline Ops and I found myself training up a new (ex Servisair) Ops Controller.
He and I hit it off straight away and I'll never forget his words "The cheaper the fare the worse the passenger".
That was oh so true, in the UK IT world Spain, particularly the 2hr rather than 2hr 30min flights, were the worst, Corfu, rather than the likes of Kos and Rhodes, was another 'lager lout' destination ... and as for the Channel Islands ... well!
Of course these days we have airlines offering fares for stupid amounts of money ... They are their own worst enemy.
