Press releases, typically prepared by public relations departments to notify the public and the press about important developments, continue to be frequently utilized tools. Press releases are essential in public relations for announcing newsworthy items, such as product launches, quarterly earnings, mergers, or important updates. As in various fields, digitalisation has changed and transformed some tools and methods in public relations. However, press releases, one of the oldest public relations tools, are still used by organisations' communication departments for the same purposes. Due to digitalisation, press releases are now posted on businesses' websites and social media pages. For this reason, the press releases published by the four airlines on their corporate websites were analysed in this study. The main objective of the research is to identify the message content in press releases and how it aligns with public relations objectives. For this purpose, all press releases issued by four airline companies in 2023 were analysed using content analysis. In this context, it was determined that airline companies issued press releases in a total of nine different categories. These categories are press releases named Public Announcement, New Route, Corporate Social Responsibility, Financial - Earnings, Innovation & Technology, New Partnership, Award Announcement, Product - Service Launch, and Sponsorship. As a result, it was concluded that these press releases also serve airlines' marketing and public relations purposes.
