Panama Canal Modifies Booking System for Neopanamax Vessels

The Panama Canal announced temporary modifications to its Transit Reservation (Booking) System for Neopanamax vessels, with the aim of providing greater flexibility to customers, improving the distribution of available capacity among different market segments, and promoting the efficient use of water resources.

The adjustments reflect the Panama Canal's commitment to its customers and to providing a safe, reliable, and efficient service. Developed after careful consideration of customer feedback and current operational conditions, these measures seek to respond more effectively to changing customer needs, while preserving the predictability and operational standards that the maritime industry relies on.

The changes will come into effect on August 30, 2026, for reservation dates starting September 13, 2026.

Greater flexibility for customers

Under the new provisions, Neopanamax vessel customers will be able to obtain more than one reservation slot for the same date, as well as slots for two or more consecutive dates. These modifications temporarily suspend certain restrictions established in Advisory A-28-2026.

A total of 63 reservation slots for Neopanamax vessels will be offered each week, including those allocated through the Long-Term Slot Allocation (LoTSA) and NetZero programs.

Customers will also retain the flexibility to exchange or substitute vessels after a slot has been allocated, provided that the substitute vessel has an equal or greater Transit TEU Allowance (TTA) capacity and applicable limits for each customer are respected. Vessels operating under alliances or sharing agreements may also participate in eligible exchanges or substitutions, provided that these operations do not cause a customer to exceed the maximum number of slots allowed.

Likewise, changes to reservation dates may be authorized as long as these do not result in a customer exceeding the applicable maximum number of slots.

Allocation designed to promote equitable access

The revised system establishes an initial distribution of slots among the main market segments of the Panama Canal, with the aim of ensuring that different types of vessels have access to available reservation capacity.

For Full Container vessels, at least five slots per reservation date will be made available, distributed according to the vessels' TTA capacity. For Liquefied Petroleum Gas (LPG) and Liquefied Natural Gas (LNG) vessels, at least three slots per reservation date will be made available for each segment, allocated according to customer classification. In the case of the Vehicle Carrier/RoRo, Bulkers, and other segments, a minimum of three weekly slots will be available, distributed according to customer classification.

These allocations function as an initial distribution of capacity and not as maximum limits per segment. When a segment does not register sufficient demand to use the available slots, the remaining capacity may be redistributed among other eligible segments, according to the order established in the advisory.

In this way, the system seeks to expand opportunities for access to slots among different market segments, without leaving available capacity unused.

Clear rules for competition and allocation

The Panama Canal will continue to apply transparent criteria in the allocation process.

Customer slot limits may only be exceeded when there are no other customers in the same market segment competing for available capacity. Slots awarded through the auction process will not be subject to the per-customer limit.

The daily auction slot will continue to be offered from the remaining capacity of inter-segment competitions at the beginning of Reservation Period 3.

While the water deficit in the Canal watershed persists, customers are advised to plan their transits using the Reservation System. A confirmed reservation continues to be the only mechanism that guarantees a specific transit date. Vessels arriving without a reservation may experience delays depending on demand and available capacity.

These measures are part of the Panama Canal's ongoing efforts to maintain a balance between providing reliable service to its customers, equitable access to available transit capacity, and responsible management of the watershed.

The modifications do not alter the Panama Canal's commitment to the safe and efficient operation of the Canal. On the contrary, they provide greater commercial flexibility to customers while allowing the Panama Canal to respond prudently to current water conditions.
