At or below FL290, the standard vertical separation for jet traffic is 1,000 feet.

Vertical separation is the vertical distance ATC keeps between aircraft to prevent collisions. For jet traffic at or below flight level 290, the standard minimum vertical separation is 1,000 feet. This spacing provides a safe margin for altitude changes and navigation accuracy while still allowing efficient use of flight levels. The other options are not the standard; 500 feet would be too small to safely separate fast-moving jets, while 1,500 or 2,000 feet are larger separations than the normal minimum at these lower altitudes. So the correct concept is that 1,000 feet is the standard vertical separation below or at FL290.
