Wayfarer is a fictional airline company in Breaking Bad. It is the airline for which Wayfarer 515, a 737 commercial airliner, was operating before the aircraft collided with a small charter plane over Albuquerque, killing 167 people. Wayfarer itself is very rarely mentioned unless in association with the plane crash, and very little information about the airline is given. (Breaking Bad Wiki)
This is my rendition of what the paint scheme for Wayfarer could've looked like. Of course, since there are no images of what the aircraft would have looked like, I went with a western feel. I may update this livery at a future date.
