With Cryanair 99.5% (or more) of the time your flights will be uneventful, on time and your bags will travel on the same plane as you. 0.5% (or less) of the time something will go pear-shaped. Often not Cryanair's fault but you will be on your own. Ground Handling staff (rarely employed by the airline) are given zero authority to solve your problem.
If your flight is cancelled they will try and fob you off with 'here's your money back, go away', (even though they are required to compensate and assist you) or come back tomorrow (or in a weeks time) when we have seats available, or get yourself to the next airport 50-100-200kms away and we'll take you on our flight from there.
But you're on your own, they won't put on a bus to get you (and the other 180 passengers on your flight) there. Not their problem. They will never book you on another airline. They will just hope you will go away.
They are profitable, which you cannot say is true of many other airlines. But their profits come at a cost, to a small percentage of their passengers.
