I think we ought to settle this one here and now - on one hand we have Beagle, old, a bit doddery, possibly getting a bit chubby and going mutton. On the other hand we have Mikey the ***** "evil empire".
Who would you rather fly you home???
Despite not having the pleasure of meeting him, Beags gets my vote every time. Even though he's an old fart.
Ryanair pushes the limit of every law they think they can get away with - with an attitude like that how much do you want to bet maintenance is cost/benefitted out as thinly as possible.
Wny do they buy new jets - less things to break and therefore less cost to maintain (for now)
