Landrum & Brown has developed an outstanding international reputation for the development of independent, accurate and useful aviation demand forecasts for airport operators around the world. Forecasting experts often remind their clients that forecasting is as much art as science. While this may be the case, Landrum & Brown forecasts incorporate both sophisticated quantitative methods and sound qualitative judgments based on its knowledge of the aviation industry, external events related to globalization and national security issues; and economic and demographic factors. The firm’s demand forecasting capabilities and experience include long-range forecasts for such major airport systems as New York, Chicago and Los Angeles; medium-term forecasts in support of financial feasibility studies; and short-term risk assessments and benefit-cost analyses for airline hubs and critical spoke markets.

The firm's financial services team includes experts in forecasting, economics, financial modeling, risk assessment, municipal finance, credit structures, capital program definition, statistics, database management, and federal funding guidelines. The firm routinely addresses complex airport financial situations, from shifting demographics and airline focus to the need for major capital resources as a result of long-deferred capital investments. Landrum & Brown has provided critical financial services to individual airports serving key spoke markets such as those in San Diego, Boston, Phoenix, Toronto and many others. Additionally, Landrum & Brown has developed hundreds of airport capital improvement programs (CIPs) on five continents in 20 countries.
