This exploratory study had two research objectives. First, it aimed to investigate digital reading on EIL materials for Thai undergraduate students and, second, explore students' perceptions towards digital reading on EIL materials. The study involved two hundred and ninety-nine undergraduate students enrolled in an aviation business management program. The EIL Digital Reading Questionnaire is to collect quantitative data, while the semi-structured interview is to collect qualitative data. The result from descriptive statistics of the questionnaire and thematic analysis of the semi-interview reported that Thai undergraduate students tended to encounter, engage, and evaluate EIL materials frequently. Most of the participants strongly agreed on perceiving the use of these EIL digital reading strategies, including encountering, engaging, and evaluating. Furthermore, the implications of the findings were applied to develop and suggest materials for aviation business management instructional practices with a focus on English as an International Language digital reading.
