The purpose of people gathering at Skytrax is to make better choices using the actual experiences of other customers who have experienced airlines. Online reviews written by customers with experience using airlines in Asia were collected. The data collected were online reviews from 27 airlines, with more than 14,000 reviews. Topic modeling and sentiment analysis were used with the collected data to figure out what kinds of important words are in the online reviews. As a result of the topic modeling, \u2018seat\u2019, \u2018service\u2019, and \u2018meal\u2019 were significant issues in the flight through frequency analysis. Additionally, the result revealed that delay was the main issue, which can affect customer dissatisfaction while \u2018staff service\u2019 can make customers satisfied through sentiment analysis as the result shows the \u2018staff service\u2019 with meal and food in the topic modeling.<\/jats:p>","DOI":"10.3390\/info12020078","type":"journal-article","created":{"date-parts":[[2021,2,12]],"date-time":"2021-02-12T18:45:00Z","timestamp":1613155500000},"page":"78","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":96,"title":["Topic Modeling and Sentiment Analysis of Online Review for Airlines"],"prefix":"10.3390","volume":"12","author":[{"given":"Hye-Jin","family":"Kwon","sequence":"first","affiliation":[{"name":"Division of Business Administration, Pukyong National University, Busan 48513, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hyun-Jeong","family":"Ban","sequence":"additional","affiliation":[{"name":"School of Hospitality &amp; Tourism Management, Kyungsung University, Busan 48434, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae-Kyoon","family":"Jun","sequence":"additional","affiliation":[{"name":"Division of Business Administration, Pukyong National University, Busan 48513, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5361-6368","authenticated-orcid":false,"given":"Hak-Seon","family":"Kim","sequence":"additional","affiliation":[{"name":"School of Hospitality &amp; Tourism Management, Kyungsung University, Busan 48434, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,2,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"466","DOI":"10.22304\/pjih.v6n3.a3","article-title":"Challenges and Opportunities of the Establishment ASEAN Open Skies Policy","volume":"6","author":"Heriyanto","year":"2019","journal-title":"Padjadjaran J.
