The 'shambles' as you put it is not being defended, Mikey, the airline as it operates normally is.
You say you've never flown with Ryanair so base your opinions on newspaper headlines and second-hand information.
In ordinary times Ryanair is a perfectly adequate carrier offering low prices for many destinations, just like Easy Jet and others.
They've messed this up as they've done in the past, mostly due to poor communication, but they continue to transport thousands to their destinations for little money or fuss.
