Under aviation passenger rights jurisprudence, airlines frequently categorize operational disruptions as "uncontrollable weather delays" to avoid financial liabilities. However, unless the Federal Aviation Administration (FAA) or civil aviation regulator halts all ramp operations, disruptions caused by delayed inbound aircraft, crew rest constraints, or mechanical defects are legally deemed carrier-controllable.
