Starlink supports in-motion use at speeds up to 550 mph (471 knots) in authorized locations. Effective November 7, 2025, this limit will adjust to 450 mph (391 knots). If this affects your connectivity needs, especially for high-speed in-motion applications, consider upgrading to a Starlink Aviation plan (20GB or Unlimited).
