S. 5446 — Cash Refunds for Flight Cancellations Act

This section requires air carriers and foreign air carriers to issue full cash refunds, including taxes and fees, for flights they cancel or significantly delay or change (defined as 3 or more hours late for domestic flights and 6 or more hours late for international flights). It mandates refunds for passenger cancellations made at least 48 hours before departure (issued within 30 days), treats non-response to offers as a refund request, requires non-expiring vouchers or credits as alternatives, extends the rules to ticket agents within one year, and applies to carriers with prior-year operating revenue above $1.5 billion (inflation-adjusted beginning in 2028).
