Effects of advanced purchase on tickets price variation: the case of the S o Paulo metropolitan area [paper in Portuguese]

This paper focuses on evaluate whether there are variations in the practice of discount in advanced airline fare purchase in regional and airlift flights and flights between the high and low season. With the aid of an econometric model and a data collection over a period of three years (2008, 2009 and 2010) of flights with origin from Guarulhos and Congonhas airports, it was observed that the advance purchase for airlift flights reflected in average discount of 37%, while for regional flights the discount of 24.3% is observed. . In relation with low season, the high season flights have larger discounts just after purchase with 45 days from the flight date. The main explanation for the results can be grounded in segmentation between passengers who travel for business and leisure.
