Utilizing a combination of machine learning and causal inference methods, we examine the specific impact of service improvements on customer satisfaction, with a focus on the online boarding pass experience. Through detailed data analysis involving several predictive and causal models, we demonstrate that improvements in the digital aspects of customer service significantly elevate overall customer satisfaction. This paper highlights how airlines can strategically leverage these insights to make data-driven decisions that enhance customer experiences and, consequently, their market competitiveness.  \nIndex Terms—customer satisfaction, machine learning, causal analysis, airlines, service-profit chain  \nI. INTRODUCTION  \nA. Industry Context  \nThe COVID-19 pandemic has significantly disrupted the global airline industry, leading to unprecedented revenue losses and slow recovery rates. As airlines endeavor to regain their pre-pandemic financial stability, understanding and addressing customer pain points becomes imperative for maintaining competitive success. This research focuses on analyzing customer satisfaction trends and identifying actionable insights that can enhance service quality across the industry.  \nB. Problem Statement  \nRecent stock performance trends underscore the pervasive challenges within the airline industry. For instance, Delta Air Lines, along with other major carriers such as United Airlines, American Airlines, and Southwest Airlines, has not returned to its pre-2020 stock valuation. This pattern indicates a uniform struggle across the sector, suggesting a widespread need for strategic adjustments in customer service approaches [1] .  \nFig. 1. Five-Year Stock Performance of Delta Air Lines (2020-2024) .  \nC. Research Objectives  \nThis study leverages advanced machine learning and causal inference techniques to examine how specific service improvements, particularly in the online boarding pass process, impact overall customer satisfaction. By integrating quantitative data analysis with model-driven predictions, we aim to provide airlines with evidence-based recommendations for improving customer experiences and, consequently, their operational performance.  \nD. Service-Profit Chain  \nA growing number of companies are placing emphasis on the Service-Profit Chain model, which underscores the importance of treating employees and customers well. This model suggests that enhancing customer satisfaction and loyalty can significantly impact revenue [2] .  \nFig. 2. The Service-Profit Chain Model Illustrating the Link between Service Quality and Revenue.  \nE. Research Methodology  \nIn this project, we focus on the latter half of the ServiceProfit Chain, starting with service value, to determine what airlines can improve to directly affect customer satisfaction. We address this through a twofold investigative process:  \n1) How can we leverage machine learning and causal models to help an airline improve customer satisfaction?  \n2) What specific features should airlines target to enhance customer satisfaction?  \nAirlines collect a vast amount of data on customer satisfaction through surveys that gauge various aspects of the flight experience, such as convenience of departure time, leg  \nroom, and departure/arrival delays. At the end of these surveys, customers are also asked to rate their overall satisfaction with their experience. We plan to use such survey data to identify the best predictors of overall satisfaction by training classification models with a variety ","cbCailqz2AvY1iOo","https://ap.wps.com/l/cbCailqz2AvY1iOo","pdf",1328703,1,7,"English","en",105,"# Introduction\n## Industry Context\n## Problem Statement\n## Research Objectives\n## Service-Profit Chain\n## Research Methodology\n# Data Collection and Preprocessing\n## Data Background\n## Data Preprocessing","[{\"question\":\"What problem does the study focus on regarding airlines?\",\"answer\":\"It focuses on enhancing airline customer satisfaction, which is essential for customer retention and brand reputation, supporting revenue growth.\"},{\"question\":\"Which methods are used to evaluate service improvements?\",\"answer\":\"The study uses a combination of machine learning models and causal inference techniques to estimate the impact of specific service changes on customer satisfaction.\"},{\"question\":\"What service area receives special attention in the analysis?\",\"answer\":\"The analysis emphasizes improvements related to the online boarding pass process as a key feature influencing overall satisfaction.\"}]","Enhancing Airline Customer Satisfaction -
