Well, no one can see what route that is or what game world you're talking about...However, FYI, 200% of all bug reports are closed on this particular matter because the player didn't check the return route demand/supply and subsequently facepalms.
Which is the real bug, IMHO. Routes with demand that are 25% on the return leg than what they are an the initial leg are a good way to make rookies flee the game. It's hostile, counterintuitive and unfriendly(note that I didn't write unrealistic).
Yet, every time that's reported as a bug, it has been closed as not a bug.Regardless, I've found that this problem is often caused by someone trying to 7 day schedule things with times throughout the day/week resulting in 2 return flights on one day and 0 return flights on a different day even though all outbound flights are on different days.
