        abstract = {Passengers who experience commercial flight delays incur a substantial financial cost; however, existing compensation processes have lengthy bureaucratic delays, lack of clarity regarding procedure, and require expensive third- party intermediaries. This study presents SkyGuard DAO, an automated flight compensation system based on blockchain technology, and built using Ethereum smart contracts deployed on the Sepolia testnet. The infrastructure supports the entire claim lifecycle, and consists of a Flask-based server built over Web3.py, with a MongoDB persistence layer and React-built front end connected to users' MetaMask wallets. Compensation payments, consistent with EU Regulation 261/2004, will be made automatically in Ether (ETH) upon submission/certification of a claim, with no manual intervention. The Developer Testing Panel will provide an ongoing means to monitor real-time flight delays and verify blockchain transactions for developer use. Results of empirical evaluation show that claim submissions can be processed in sub-second time, all transactions are completely verifiable on Etherscan, and that the entire claim from start to finish will take 90–120 seconds to complete, as compared to the industry average of 5–30 days.},
