The problem with using ramjet propulsion on commercial airliners is that the engine requires air to be moving through it at supersonic velocity before you start the thing up, and I don't think anyone has found a good way to solve that problem on something as gargantuan as a 747 or Airbus A3-anything.
I'm not an aerospace engineer, though, so don't take that as fact.
