Get over it, Ryanair do a fantastic job moving people from their local airport to where they want to go, safely and cheaply on newish planes with no previous owners.
What has that got to do with the OP's post? He didn't cast doubt on their ability to move people in aeroplanes.
Anyway, back on point, even that
we-want-to-be-MOL's-children outfit Jet2 offer online check-in 28 days prior to the flight.
Wizz's window is 30 days.
Easyjet's is also 30 days.
Ryanair's seven days is farcical.
The only airline I can find that is worse is the bottom-scraper known as Spirit Airlines with whom you have a check-in window of 23.5 hours prior to departure.... correction, 23 hours
Online check-in begins 24 hours prior to departure and ends an hour prior to your flight's scheduled departure.
