Your ticket purchasing process can be an immensely frustrating experience, dodging a horde of dark patterns coming at you from every direction.
Your check-in process may be a horrible user trap (you must check-in from home, and print a boarding pass there. Said check-in closes 4 hours before takeoff, and there's a 40 Eur fee if you do it at the airport) which the EU had to explicitly ban.
Your refund/rebooking process may be outright illegal, planning on passengers being unaware of their full rights.
In the end, your safety record may not come into play at all: I don't care if your planes crash or not, because I'm never, ever, boarding one again, and neither will anyone who listens to me.
Their cabin comfort, I will admit, leaves a lot to be desire. One gets what one pays for in that respect.
