Holiday Extras Rebuilds App With Codex, Lifting Conversion 32.5%

Summary
Two weeks of work with OpenAI Codex produced a rebuilt Holiday Extras main app, a project the company said previously would have taken more than six months.
32.5% higher open-to-book conversion followed the rebuild, while the app’s error rate dropped to 9% from 19% and releases shifted from one major annual update to weekly launches.
Codex let product and operations staff turn customer knowledge directly into software, with engineers focusing on architecture, APIs, security and reusable building blocks across iOS and Android.
Holiday Extras is extending the approach beyond the app, using ChatGPT Enterprise and OpenAI models for personalized experiences, faster customer-feedback fixes and automated airport-transfer issue tracking.
