Harrogate - I am familiar with the concept, I was merely correcting the ascertion that Jet2 didn't market itself as low cost, which it does for the reasons you alude to.
In effect though looking at the routes/frequencies that they offer to some destinations i.e the Greek Islands isn't it actually incorrect to bracket them with the likes of Ryanair or Easyjet. Both of whom one would readily accept as LowCost Operators, when in fact what they are doing is block selling to tour operators and selling the rest of the seats themselves. A smart move in my humble opinion.
