Wrong Citation in the Main Text

In the original publication, references 28–31 and 34–49 were not cited in the correct positions, and reference 4 was inappropriately cited in Section 3.4. These citations have now been corrected in the following sections: Section 2.2 (Smart Airport Systems), Paragraphs 4 and 5; Section 2.3 (Customer Satisfaction); Section 3.4 (Predictive Data Analysis), Paragraphs 1–6; and Section 4 (Discussion of the Study), Paragraphs 1 and 2. Additionally, references 59–65 have been renumbered in Section 5 (Implications and Suggestions for Future Studies), Paragraph 1. Reference 66 has also been moved after reference 57, with the numbers updated accordingly. As a result of these changes, the order of some references has been adjusted.
