Worst airline

How do they run this business, waiting to check in for a flight but because I refuse to “buy a seat “ I can only do it 24 hrs before I fly, so what did I purchase online ? This is the worst airline I have ever dealt with, the other alternative from my airport in France is EasyJet who I normally use, totally different company, Ryanair still have a lot to learn, you can only rip-off people for so long !
