Norwegian Air Shuttle’s announcement about its plans to launch transatlantic flights from Ireland and that it is nearing a deal with its—much larger—Irish low-cost counterpart Ryanair about feeding its long-haul network makes one wonder: Is more going on?

Both are fanatical in their efforts to drive unit costs down, growing rapidly (much to the annoyance of Europe’s legacy network airlines) and have a proclivity for Boeing.
