Yes, a business—such as a hotel, airline, or restaurant—can legally charge you 100% of the booking cost for a "no-show," provided this policy was clearly outlined in the terms and conditions at the time of booking. For non-refundable hotel rates, the hotel has "held" that room for you, preventing them from selling it to another guest; therefore, they are entitled to the full amount if you do not arrive. For restaurants, particularly high-end establishments with pre-paid bookings or "cancellation guarantees," a no-show fee can often equal the full price of the tasting menu. In the airline industry, if you miss the first leg of a flight without notifying the carrier, they will not only keep the full fare but also typically cancel all subsequent legs of your journey (the "no-show" cancellation rule). To avoid these charges in 2026, it is essential to read the "Cancellation Policy" before clicking buy. Most businesses require 24 to 72 hours of notice to avoid a penalty. If an emergency occurs, it is always worth calling the manager directly, as many will offer a credit or a partial refund as a gesture of goodwill, even if the policy says 100%.
