Looking at flightstats.com, I saw Shuttle America. I then looked for pictures here because, back in the day, different airlines had different tail colors. Shuttle America has eiher DL or UA tail colors. SkyWest does a similar thing. What is the advantage of having a smaller airline, calling it a different name, but keeping all the same colors as the parent airline?
