I don't know for certain, but I'd guess WOW does the same thing Norwegian does: hiring staff on short-term contracts from places where labor is cheap (IIRC Norwegian hires its flight-deck crews from Estonia and cabin attendants from Thailand) in order to get low wages and avoid the overhead of full-time employment, registering most business operations in places like Ireland with favorable tax situations, and then ensuring most flights pass through at least one second-tier airport with low fees. Combine with being able to take advantage of half-in, half-out type EU pseudo-member benefits and you've got the makings of a profitable low-cost carrier.
WOW also appears to make do with a shoestring fleet -- they have only three long-haul planes, total, at the moment and seem to be relying on the range of much smaller A321s to do a lot of their US/Canada destinations.

Every time I've flown a WOW air flight, the attendants were Icelandic. So I don't think that's true.
