Shippers, the ultimate customers of the global air cargo supply chain, are being invited to join The International Air Cargo Association (TIACA) free of charge. The ground-breaking initiative recognises the importance for air cargo service providers to gain a more complete understanding of the needs of shippers, TIACA said in a statement. TIACA says it will provide a forum to shippers to get closer to existing and prospective air logistics partners to exchange ideas, discuss changing needs and challenges, and to develop new business opportunities.
