Interline or Interlining

An interline is a legal agreement, called a 409 agreement, between different household goods carriers to transport each other’s shipments. Typically, this arises when each carrier has a partial load destined for the same city and it doesn’t make economic sense to run two partially full trucks instead of one full van. Commercial airlines developed the interline system to ensure efficiency and profitability. The interlining company pledges to provide the booking carrier’s customers with the same level professionalism as the booking carrier themselves. Arpin of RI has an interline agreement with Wheaton Van Lines, Bekins Van Lines, and Stevens Van Lines to provide consistent transportation solutions to all corners of the US.
