People think that scheduled routes are much more used than non-scheduled routes. The reasons are as follows.

1. Goods on regular routes are more stable, with less uncertainty and fixed prices, while goods on irregular routes are affected by external factors and are mostly transported at low cost.

2, regular routes, refers to the use of fixed ships, sailing according to a fixed schedule and port, and operating passenger and cargo transportation business at a relatively fixed freight rate. Regular routes, also known as liner routes, mainly carry groceries.

3. Unscheduled routes are temporary routes selected according to freight needs. Ships, schedules and ports of call are not fixed, mainly engaged in the transportation of bulk and low-cost goods.
