The problem is in people's understanding of the way a code share works, not in their knowledge of who is operating a flight. For example, I've talked to passengers who believe if they buy a ticket on a United website, and hop on a CRJ painted in United colors, that there is some sort of deep connection to United, as opposed to just a shallow little marketing agreement. They believe there is a connection to United's standards of training, experience, service, quality, etc. This isn't purely by accident, or coincidence. The marketing department at United wants people to have that impression. The aircraft are painted in their colors for a very specific reason. I have no problem with people being informed that the only connection between a regional and a major is paint and paper. However, as others have said, this legislation will fail in that endeavor.
