Wayfarer Airlines is a fictional airline central to the universe of Vince Gilligan's shows, known for the fatal Wayfarer 515 crash in Breaking Bad, a major plot point, and appearing as an Easter egg in his new series Pluribus, serving as a nod to that connected universe.
While a real company called Wayfarer Aviation existed and went bankrupt, the airline itself is a storytelling device, linking the worlds of Breaking Bad, Better Call Saul, and Pluribus.
