Air Tracking
Ordered milestones for air cargo. Each row shows what the milestone means and where it comes from.
No loading milestone is shown for air.
Completed steps carry status: complete and a completed_on date. Steps not yet reached are pending (or processing while underway) with no timestamp — missing events are never backfilled. Assigning a shipment alone completes nothing; each milestone completes only when operations records it.
