%X the main goal of this paper is to provide a preliminary analysis of the code share agreement involving varig and tam. the data used is concerned about rio de janeiro-s£¿o paulo air shuttle, one of the main brazilian domestic routes. we use data envelopment analysis (dea) with double frontier approach, to compare the conditions in october 2002 (before the agreement) and april 2003 (after the agreement). as dea models are comparative ones, we need to extend the analysis to all the other companies flying in the same route. from the results we can say that the agreement did not improve the service provided to passengers
