⚖️ Why This Rule Exists: Statutory Medical Safeguards & 14 CFR Part 382 Accessibility Protections

Under federal aviation law and disability access regulations, medically necessary items, prescription pharmaceuticals, assistive equipment, and life-supporting supplies are granted explicit exemptions from standard baggage quotas and liquid volume limits to protect passenger health during travel.
