Ancillary services have become a major source of revenue for airlines, generating $42.6 billion in 2013. Both full service carriers and low cost carriers have benefited from fees for items like baggage, seat selection, in-flight entertainment and hotel/car services. Global ancillary revenue per passenger was $13 in 2013, and airlines expected to earn $5.94 per passenger in profit from these services in 2014. Technology partners are important for airlines to effectively integrate new ancillary services and distribution channels to maximize revenue from customer fees.
