My Deam Vacation

I see that NASA is planning to replace the Space Shuttle with a dual system, sending cargo and supplies up in one rocket and returning to the classic style with crew and capsule modules in a second rocket. Cheaper and more efficient, and allows for different systems needs for the different payloads.

Doesn’t this also make sense for airline travel? At any given time, there are multiple airline companies flying from and to the exact same destinations only minutes apart.
