Inexplicable - a good word. Anybody who has seen previous Ryanair use of statistics could hardly be surprised. Whether it be airport charges, comparative salaries, their profits, or anything else, Ryanair are totally self-serving in their use of numbers (and of the English language).
They are also utterly deadly in their abuse of anything and everything that stands between the truth and what they want the story to be. There is nothing new here. Claims about "superiour" pilot pay in Ryanair are made repeatedly and they want, positively want, a public debate about pilot salaries.
Their comparative table should be treated with the derision it deserves.
