At its web site, www.tmmlines.com, TMM Lines has linked its sailing schedules to the line's own ship scheduling computers used by the operations department. This means schedules on the web site are in real time and up-to-date. In the past, sailing schedules were posted once a week and nothing changed until they were replaced by the new schedules the next week.
Other TMM web site services include container tracking, bill-of-lading printing, and customs clearance status for shipments arriving in the United States.
