Scandinavian Airlines (SAS) is to save £1.8m by outsourcing voice services to SITA.
SITA will be the sole provider of the airline's international voice telecommunication services, with SITA's contract replacing more than 100 existing contracts with other suppliers.
The agreement will save SAS £1.8m, with SITA providing services to 800 users in 40 locations across 23 countries.
Elisabeth Ragna, chief financial officer at SAS, said, "As is the case at many airlines, years of evolution at SAS and changing operational requirements had left us with a complex range of systems, providers and contracts for our voice services.
"With SITA, we reduce the complexity, have greater visibility of our costs and will benefit not only from significant cost savings, but also greater flexibility to meet our ever-changing operational needs."
