This paper aims to evaluate the efficiency of Brazilian air carriers. Data Envelopment Analysis (DEA) approach is used to determine the efficiency of each airline company, comparing its outputs with available inputs. Scale of operation is taken into account. The aim is to measure each company's performance, comparing its relative efficiency to all others included in the group under investigation. It is possible to evaluate each carrier efficiency over the years (1998, 1999 and 2000), assuming that the same company is a different one in different years. Both efficiency index and targets choice are performed. The proposed approach, that uses a Multiobjective-DEA problem, allows choosing targets belonging to the feasible set of efficient companies.
