How Virgin Atlantic ships faster with Codex
Curated by the Inblix editorial team
Virgin Atlantic used OpenAI’s Codex to overhaul its mobile app in time for the high-stakes Christmas travel season, achieving near-perfect unit test coverage and zero critical bugs at launch. The tool slashed legacy code refactoring from two weeks to just 30 minutes, reducing codebase sizes by up to 80%. Developers built a full front-end app from a Figma prototype in a week, outpacing backend ticket readiness. Data teams are also using Codex to de-risk database migrations and prototype custom tools directly on the data warehouse. Why it matters: This case shows that AI-assisted coding isn’t just about speed—it’s enabling enterprises to hit aggressive deadlines without sacrificing quality, a rare feat that’s changing how teams plan releases.
