Aviation Services Ireland

Aviation Services Ireland, known as ASI, gives revenue accounting support to airlines. It audits interline billing and related fees. It says it has done this work for twenty-nine years. Its head office is in Dublin, Ireland. It has operational offices in Winston-Salem, North Carolina, and Olsztyn, Poland.

ASI was set up in 1992 as a subsidiary of Aer Lingus. In 2002 it was sold to its management. A US branch opened in 2006 and was joined by experienced staff from US Airways. A branch in Poland opened in 2015 to support the work done in Dublin.

The core service is interline billing support. Interline means billing between airlines when a passenger flies on more than one carrier. ASI says it is expert in proration, which is the split of revenue between those carriers. It says it audits interline billing for over 35 major airlines. It also offers SIS file conversion services.

ASI also does sales and fare audits. It describes a second pass audit that looks for recoveries that other vendors leave behind. It audits ticket taxes with its own tax application. It checks frequent flyer programmes, including the rates billed and the award billing. It also audits cargo billing for errors and overbilling.

Other services are training, advice and business support in revenue accounting. The team can review a revenue accounting process, compare it with others and suggest fixes. ASI also offers remote health checks of revenue accounting systems. It provides business process support for airlines with staff shortages.

ASI says its audit services use a savings-based pricing model. That means an airline pays from the savings found, not a direct fee. The company has built its own web based tools for audits and data analysis.

ASI is a member of the IATA Partnership Programme and a participant in SIS. It is an associate member of the Airline Clearing House. Enterprise Ireland, an Irish government agency, supports its work. The website lists the services in detail.
