The problem is a lot of people book Ryanair thinking they're going to save money and end up sucked in to these dark patterns.

I once flew from London Stansted (or maybe it was Luton?) to Dublin instead of from Heathrow with Aer Lingus to save a few bucks, and it never ended up saving me anything in the end.

With Aer Lingus the cheapest ticket includes 10kg of checked luggage, which is a nice middle ground between a tiny bag you can shove under your seat and a 23kg luggage

And Ryanair are not even cheaper most of the time unless you're prepared to fly at unsocialable times and forgo luggage.

Ryanair even seem to deliberately separate seats for adult passengers on the same booking so they can charge you extra to sit together...
