Alliances development
– No individual airline has developed a truly global network. Thus the network is
virtually enlarged by interlining with partner carriers and become part of
multi-HS systems.
• Vertical product differentiation
– This is affected through in-flight and ground service, electronic services
(Internet check-in) and travel rules to cover all possible market segments.
• Yield management and pricing
– To support product differentiation, pricing and yield management is
sophisticated, with the aim of maximizing the network revenues.
• Distribution system:
– The complexity of the distribution system described above is technologically
supported by external companies called Global Distribution Systems (GDSs).
– Among the most diffused GDSs are: Galileo, Amadeus, WorldSpan, Sabre.
