Blind Pew
I sit in the scenic end of a plane all day and during turnarounds can see that Ryanair have many bags tagged and put in the hold after being handed over at the aircraft stairs. I've regularly counted 30+ neatly lined up by the stairs. The notion that 189 can board a 737 with their carry on and their hand bag/man bag is absolutely hilarious.
The confiscation of bags at security is nothing to do with airlines. It has been a long time since I've seen this policed at any airport and your experience is certainly not what I experience weekly commuting with easyJet.
172Drive - really? Twenty years ago 'sleazyJet' was mildly amusing. Today? Can you explain how the baggage policy is shambolic. It makes perfect sense to me.
Just as a comparison:
737 non sky interior, 189Y = 78.49in2 per pax
737 with sky interior, 189Y = 74.20in2 per pax
A320 non pivoting bins, 180Y = 84.70in2 per pax
