US Regulations: DOT 24-Hour Rule and CARES Act Timelines

In the US, the Department of Transportation (DOT) enforces strict rules. The 24-Hour Rule lets passengers cancel within 24 hours of booking for a full refund without fees, provided the ticket was bought 7+ days before departure. For airline-initiated cancellations, refunds are mandatory.

2026 DOT Updates: Expanded to cover more international flights from US airports, with electronic refunds required in 7 days (credit card: 20 days max). The CARES Act mandates refunds for involuntary cancellations (e.g., mechanical issues) within 7 days for credits or 30 days for cash--no vouchers unless accepted.

Statistic: 95% of US cancellations qualify for refunds. Mini Case Study: In 2025, passenger Jane Doe won a $1,200 refund from Delta after a 48-hour delay in processing her involuntary cancellation claim via DOT portal--processed in 10 days post-complaint.

EU261 Compensation: Time Limits After Cancellation

EU261 protects passengers on flights departing EU/UK airports or by EU airlines. Compensation (€250-€600) applies to controllable cancellations with <14 days' notice.

Time limits vary: UK (2 years post-Brexit), France (6 years), Germany (3 years). Statistic: Average payout €350; 70% claims approved.

Mini Case Study: A 2024 Ryanair cancellation claim filed 18 months later succeeded in France under 6-year limit, yielding €500 per passenger despite airline denial.

International Rules: Montreal Convention and IATA Guidelines

The Montreal Convention sets a global 2-year statute of limitations for international flight disruptions, including cancellations, delays, and baggage. It overrides airline policies.

IATA recommends 14-30 days' notice for cancellations to avoid compensation. Statistic: 40% international claims denied due to time limits.

Comparisons:

Airline-Specific Policies: Low-Cost Carriers vs Majors (Comparison)

Common Pitfalls and Statute of Limitations Warnings
