What is the standard vertical separation for aircraft operating above FL290?

Vertical separation is the height difference kept between aircraft to prevent collisions. The standard minima are set so air traffic control can reliably separate flights under instrument conditions. Up to and including flight level 290, the required separation is 1,000 feet. Above that level, the minimum increases to 2,000 feet to account for altitude-keeping variances at higher altitudes and the traffic patterns typical on high‑altitude routes. So, for operations above FL290, the standard vertical separation is 2,000 feet. For example, flights at FL300 and FL320 have a 2,000-foot difference, meeting the rule.
