Yes there are a few pay checks which hit 7 or 8 grand. There are other months where you earn little and at least one month where you earn nothing. Not a single euro.
Over 12 months the net pay is modest and doesn't take into account many business related expenses many other airlines would cover. The net pay is also under scrutiny in many jurisdictions as are the social payments.
Brag if you want but please do so with a health warning, it is not fair to anyone considering joining Ryanair to be presented by you solely with figures of 8,000 euro.
