Studi's point, that we do not know what is going to happen next, is spot on. However despite whatever we might individually wish (obviously the majority of us do not work for Ryanair), a lot of experts do think they will be amongst the survivors.
Look at the US, where the fuel price is hurting even more due to there being no currency gains partially offsetting the increase. The company that is doing best is Southwest. Whilst we all know there are lots of differences, particularly in company culture, fact is that Ryanair has openly based itself on the Southwest model.
