FlightSense: An End-to-End MLOps Platform for Real-Time Flight Delay Prediction via Rotation-Chain Propagation Features and Agentic Conversational AI

Aditi J. Shelke, Nitin P. Hazarani, Renuka J. Shelke, Yash M. Kamerkar

Tracking delays through aircraft rotation chains via tail numbers raises prediction AUC from 0.732 to 0.879 in a deployed real-time system.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Version 2 introduces 11 delay propagation features derived from aircraft rotation chains via tail-number tracking, yielding the dominant performance gain (AUC 0.732 to 0.875) and surpassing the single-stage XGBoost baseline reported by Zhou (2025).

C2weakest assumption

That tail-number tracking in the BTS data accurately reconstructs true aircraft rotation chains without missing connections, data errors, or selection bias that would make the derived propagation features non-generalizable beyond the 2018 training period.

C3one line summary

FlightSense improves flight delay prediction to 0.879 AUC by adding aircraft rotation-chain propagation features and weather inputs to XGBoost, then deploys the model with a live conversational AI interface on AWS.
