This work addresses the current analysis needs at Barcelona-El Prat airport due to the lack of official data publication, with the main objective of shedding light on the current situation of passenger capacity. In addition, it addresses the discontent of the local population in the face of possible expansions of runways and terminals. The document is divided into blocks to make it easier to understand. The first points describe the objectives and the current situation of the airport, offering an initial idea that is necessary to understand the purpose of the study. The methodology then presents a guide to the phases to be followed in order to carry out a similar study, which could be applied to other airports. Subsequently, the application of this methodology is detailed, including the results and calculations obtained from the data of Barcelona-El Prat airport, which will be used to draw conclusions. The sources of theoretical content include reference books on the sector, as well as articles and studies carried out prior to the publication of this work. The methodology begins with the objective of obtaining a design hour and the corresponding number of passers-by. Afterwards, calculations are made of security tables and filters, addressing all the processes from data collection and analysis to processing capacity calculations. This methodology has been created with the idea that it could be applied to other airports to analyse passenger capacity and obtain conclusions on saturation. The methodology includes a discussion of the criteria for establishing the design time and a description of the methods currently used. It also presents an algorithm developed to predict the flow of passengers per minute at the airport, based on sigmoidal probability corbes, using as input a time schedule. The conclusions of the study indicate that Terminal 1 of Barcelona - El Prat airport is saturated, while Terminal 2 is not. Furthermore, possible solutions and future lines of work to tackle this saturation are offered. However, it should be noted that the data used in this study are not official due to a lack of transparency on the part of the airport's managing body, and therefore the conclusions must be validated and corroborated in an official context.Objectius de Desenvolupament Sostenible::9 - Indústria, Innovació i Infraestructur
