Regardless whether the news about WOW coming back are true or not, is there really a future for these stopover flights via Iceland? Air Transat and TAP are already flying across the Atlantic with their Neo LR-s. JetBlue is about to start and many more to follow, I'm sure. Setting up a new company based on this model is unwise, IMHO. However, making a buck on the model while it can last (see my post above about WZZ/Frontier) would make sense if it's done by established operator(s).
