Expansion of NAT Reduced Lateral Separation Delayed
Under Phase 2, all routes above FL350 will have reduced lateral spacing, leaving only a couple of tracks—spaced at 50 nm—for everyone else.

Phase 2 of the reduced lateral separation minimums (RLatSM) expansion plan in the North Atlantic Tracks (NAT) has been further delayed by four weeks, to February 1. A new bulletin from the NAT management group confirms the Phase 2 implementation day but does not provide a reason for the extended delay.
