This study examines the potential benefits of an English-for-Specific-Purposes (ESP) program for airline cabin services incorporating ChatGPT and individualized coaching. A 10-session intensive course, designed based on interviews with experienced flight attendants, combined classroom activities and ChatGPT-driven assignments to enhance students’ English communication and service skills. Ten preservice college students participated in the experimental program, which significantly boosted their confidence and self-efficacy in English. The integration of AI tools like ChatGPT complemented traditional teaching methods, promoting interactive and autonomous learning. The findings underscore a shift from static ESP materials to dynamic, learner-centered methodologies supported by AI, addressing critical gaps in ESP education. Key factors for successful learning included self-directed learning, adaptability to AI, and effective time management, with underperforming students showing notable improvement. This study highlights the evolving role of technology in education and the importance of tailoring programs to leverage AI’s interactive capabilities. By integrating AI tools and learner coaching, the program demonstrates a promising approach to meet modern educational demands. These insights support the adoption of AI-enhanced ESP programs and emphasize the significant influence of learner characteristics on outcomes.
