Passengers unable to determine airline liability and compensation rights when flights are cancelled across multiple carriers

When a passenger's initial flight is cancelled and they're rebooked on a different airline, they face confusion about which airline is responsible, what compensation they're entitled to, and how to navigate conflicting liability claims between carriers. Current solutions fail because airline customer service representatives often deflect blame, compensation eligibility varies by jurisdiction and airline, and passengers lack clear guidance on their legal rights in multi-carrier scenarios.
