A Booked Slot Is Not a Locked Slot: Maersk Clears Unshipped Bookings Five Days After ETD
From 15 October, Maersk changed the clock on bookings that never materialise: where five days or more have passed since the first vessel's estimated time of departure (ETD) and the cargo still has not shipped, eligible bookings may be cancelled automatically. The wording is careful — "eligible bookings", "may be cancelled" — so this is not a blanket sweep on day five. But once the trigger is met, the party executing the cancellation is the system, not a customer service desk. Read plainly, a grey buffer that had existed for years has just been removed.
The old routine was familiar to everyone in the trade: the container missed the vessel, the booking stayed open, someone spoke to the carrier, and a rollover was negotiated. That buffer is now five days, and nobody will call on day six. The carrier's stated purpose is in the notice itself — release unused capacity sooner so it can re-enter allocation.
The timing makes this hard to absorb. Xeneta's September scorecard put global schedule reliability at 27%, down two percentage points from August, the fourth consecutive monthly decline and level with the low set in February. Average vessel delay rose to six days, 2.4 days more than at the start of the second quarter. By trade the picture is starker: Far East to Europe fell to 4% on-time with average delays of 9.9 days, the weakest since September 2021; Far East to North America held at 20% with delays of 6.9 days. At Shanghai the anchorage queue shortened from 101 to 86 vessels while waiting time lengthened from 1.9 to 2.7 days — a shorter queue that takes longer to clear. Cargo booked but not loaded is no longer an exception; it is routine, and the new rule sits directly on top of that routine.
Two misreadings cost the most.
The first is treating a rollover as a formality. Once a booking is cancelled by the system, the booking number is dead. This is not an edit to the sailing date; it is a fresh claim on capacity at today's rate and today's schedule — and European services are planning to blank roughly 17% of sailings.
The second is reading "automatically cancelled" as "no charge". What the system reclaims is the slot, not the liability. Where cargo failed to load and no timely cancellation was filed, a no-show charge can still apply. The contract and confirmation terms are explicit on this, and the invoice will not care that a system did it.
For our own operations at A-Choice, the booking ledger needs three changes. First, carry ETD and the ETD+5 line as a field of their own rather than folding them into "scheduled departure", and set internal alerts at ETD-3 and ETD-5 — the action has to happen before the vessel sails, not after. Second, split "booked" from "loaded" and put "gated in / released" between them; only loading counts as landed. A ledger that tracks booking status is a ledger that reassures without informing. Third, add an owner-and-action column stating, before the deadline, whether the booking is being rolled to another sailing or formally cancelled — and filed through the portal or EDI, because a verbal request carries no weight in a later dispute.
One distinction is easy to miss: for cargo that genuinely slips but should keep its slot, notifying carrier customer service within the five days after ETD is the only action that preserves validity. Skip it and the system applies the rule; there is no discretion left to appeal to.
One level up, this changes peak-season habits. Reserving extra bookings as insurance used to be almost free. Now the carrying cost of a redundant booking is a hard reset after five days plus potential no-show charges, so over-booking has become more expensive than being caught short. The steadier approach is precise slotting plus a named alternative: a primary booking tied to confirmed cargo, and a second carrier's sailing and rate already quoted in writing rather than sourced in a crisis.
It is also worth adding one line to customer quotations: slot validity is confirmed on loading, and bookings unshipped five days past ETD may be cancelled automatically. Unpopular, but better said upfront than explained after a delivery date collapses.
