Regional airlines typically have cancellation policies that vary by airline and fare class. Generally, passengers can cancel or change their reservations, but fees may apply, depending on the timing and fare type. Most airlines offer a 24-hour grace period for full refunds. Afterward, cancellation fees may range from a nominal charge to the forfeiture of the entire ticket value. Flexible or higher-tier fare classes often allow more lenient changes with reduced fees. It's crucial to review the Regional Air Cancellation policy before booking and consider purchasing travel insurance for added protection against unexpected cancellations or changes.
