Changes are expected in North Atlantic operations, with some outlets reporting changes as early as 2024 and others referencing updates in 2025 and 2026. The nature of these changes includes updates to oceanic clearances, routes, and procedures, such as the introduction of NAT CPDLC route uplinks and the removal of Blue Spruce routes. New guidance and resources, including a North Atlantic document and plotting chart, are being made available to support these changes.
