Ryanair are a perfectly good airline when things go according to plan.
I tend to disagree, they are not perfectly good they are perfectly cheap. No frills, no luxury, no extras but a basic means of transportation at a very low rate. Perfectly adequate, but far from good.
Moderate issues (delays due to weather) were handled much more professionally by FR compared to some other much more expensive airlines I experienced.
And if things go wrong, even companys like LH can sometimes simply leave you to your own devices. Even if you are a gold member with a business ticket they may not offer you what they are obliged to by law (food, drinks, hotel...) !
