this interpretation is bollocks. like hugh and RSJ mentioned below, there's no priority boarding for people with kids, the elderly or ill. but there is priority boarding for people who pay for it and only travel with hand-luggage - the second criterion eliminating almost anyone who might need priority boarding. it's arrogant bullshit that writes off the notion that anyone might have needs beyond those of a healthy, childless celtic tiger brat.
i hate ryanair and the scramble for seats and the bumpier-than-bumpy flights. and i never, never book with them - aer lingus is only marginally more expensive for most journeys i make, and a world apart in terms of the experience, which i find bad enough anyway - but sometimes group travel means i don't have a choice. i think cheap shorthaul flights are an environmental scourge, so i'm not even grateful for that.
Is there first class on Ryanair? - No
Is there Ryanair miles? - no
Is there a gold circle lounge or any of that shit? - no
So my interpretation isn't bollocks.
And if your so uptight about everything that unassigned seating causes you problems I'd say your better off at home with your embroidery
