Inspiration

Flight disruptions create confusion at the exact moment travelers are under time, cost, and information pressure. Flight Delay Assistant turns scattered rules into a clear, immediate plan.

What it does

The app asks only facts that can change eligibility and returns the exact complete set of supported remedies across federal rights, airline commitments, and possible requests. Every result explains why it applies, its value or calculation, evidence, deadline, official source, and next step. Travelers can prepare an airport script or written request, open verified contact routes, save evidence, and schedule follow-ups without an account.

How we built it

The native iPhone app uses SwiftUI, Swift 6, SQLite, CryptoKit, LocalAuthentication, and UserNotifications. A versioned U.S.-focused policy library contains 181 carrier records and 1,480 validated rules. A deterministic exact-remedy oracle executes all 1,480 production scenarios and fails for either a missing remedy or an unsupported extra remedy.

Codex and GPT-5.6

GPT-5.6 through Codex was the core build-time engineering collaborator: shaping the product and data contracts, implementing the deterministic engine and native experience, constructing policy tooling and exact-set validation, diagnosing failures, and packaging the signed iOS candidate. Traveler eligibility is deterministic and source-backed; generative AI does not invent eligibility decisions.

Challenges and learning

The hardest problem was proving completeness, not merely returning one plausible benefit. We built exact-set validation so every supported scenario checks both missing and unsupported remedies. The product remains local-first and useful offline.

Limitations

U.S.-focused informational guidance, not legal advice. The MVP does not claim automatic live tracking, autonomous claim filing, guaranteed compensation, or universal worldwide coverage.
