Travel data researcher and publisher
Caden Sorenson runs Travel Vient, an independent travel research site built on a verified database of airline baggage rules, airport connection times, cruise line policies, and eSIM plans. He built the verification pipeline behind it: each record is read from the company or government page that publishes it (connection times: OAG data via ExpertFlyer), stored with that source link and the sentence it came from, and re-checked on a schedule. He is a senior staff engineer with 15+ years building software, a Computer Science graduate of Utah State University, and based in Logan, Utah.
Figures link to the source they were read from and show the date last checked; some cite a travel publication or aggregator rather than the company.
