Understanding how operational procedures and demand growth can influence the check-in level of service (LoS) is an important issue for airport operators, but the importance of these factors has never been determined. With the aim of filling this gap, this paper proposes a method to evaluate the main variables that can influence the LoS of an international airport check-in. The methodology used for this study included the collection and processing of data, infrastructure analysis, software simulation of 273 scenarios and non-linear regression. São Paulo–Guarulhos international airport, Brazil, was used as a case study. The main results suggest that, among operational procedures, the processing time at counters is the most important factor, followed by the number of counters per airline, the use of self-service technologies and the opening time of the check-in desks. Airport operators must be aware of increases in flight load factors and the addition of new flights to adjust the need for counters for each airline.

机场值机服务水平决定因素评价方法

了解运营程序和需求增长如何影响值机服务水平 (LoS) 是机场运营商的一个重要问题，但这些因素的重要性从未被确定。为了填补这一空白，本文提出了一种评估影响国际机场值机服务水平的主要变量的方法。本研究使用的方法包括数据的收集和处理、基础设施分析、273 个场景的软件模拟和非线性回归。巴西圣保罗-瓜鲁柳斯国际机场被用作案例研究。主要结果表明，在操作程序中，柜台处理时间是最重要的因素，其次是每个航空公司的柜台数量，自助服务技术的使用和值机柜台的开放时间。机场运营商必须意识到航班载客率的增加以及新航班的增加，以调整每家航空公司对柜台的需求。
