Container lines cooperate on selected services by sharing vessel space and coordinating parts of their operating networks. This can expand the services a carrier offers without requiring it to operate every vessel itself. For shippers, the practical questions are the available sailing, port calls, transshipment plan, transit time and responsibility for the booking.
A carrier partnership does not mean that every carrier in the group offers an identical route or schedule. Service structures change, so check the itinerary and operating carrier for the shipment being booked.
| Network or cooperation | Carriers | What to understand |
|---|---|---|
| Gemini Cooperation | Maersk and Hapag-Lloyd | Their operational cooperation began in February 2025. |
| Premier Alliance | Ocean Network Express (ONE), HMM and Yang Ming | The carriers announced a five-year partnership beginning in February 2025. |
| OCEAN Alliance | CMA CGM, COSCO Shipping, Evergreen and OOCL | The carriers announced their Day 10 service product in January 2026. |
| MSC network | MSC operates its own main East–West network, with some separate cooperation arrangements | MSC’s standalone network replaced its former 2M vessel-sharing agreement with Maersk. |
The 2M Alliance is historical; it should not appear in a current membership list. Likewise, a 2017 route count, capacity share or port-call forecast does not describe today’s schedule. Check the actual service at the time of booking.
A booking may be sold by one carrier and transported on a vessel operated by another. Shared services can affect which ports are called directly, where containers are transshipped and how a disruption is handled. Check the commercial terms, documentation and customer contact against the carrier named in the booking and transport contract.
When comparing freight quotes, ask:
Use the latest carrier schedule and the complete quote for the route. Alliance membership is useful context, but it is not a substitute for shipment-specific service details.
