FlightSurety is a decentralized application that offers flight delay insurance to airline passengers. This project is a learning exercise and will not be deployed to the Ethereum network. In short, mock oracles will provide flight status information to this Dapp and if a flight is delayed due to airline fault, passengers will be paid 1.5 times the amount they paid for the insurance. The dapp is managed as a collaboration between multiple airlines.
In light of this project being purely for learning purposes with no intention of ever becoming published, I make the assumption that flight numbers or IDs are unique within an airline. The front-end only exercises part of the dapp for a single airline and could be improved greatly. It is merely to demo a couple features and understand how everything fits together in a dapp.
From Udacity:
Learn to build a Dapp with multiple smart contracts which are autonomously triggered by external sources, and which handle payments based on flight delay scenarios.
