How to Use the Flight No-Show Penalty Calculator
If you book a flight and something comes up so you never make it to the airport, that's a "no-show" — and it's treated very differently from calling ahead to cancel. This calculator takes the price you paid and your fare class, then estimates the penalty the airline keeps and the refund you can realistically expect back.
Fare classes generally fall into three buckets. Basic Economy fares are cheap but almost never refundable on a no-show — the ticket's value is typically forfeited entirely. Main Cabin / Standard fares keep a portion as a penalty and return the rest, often as a travel credit rather than cash. Refundable fares carry little to no penalty, which is why frequent-schedule-change travelers pay extra for them. Add any change or processing fee separately for a more accurate estimate.
Actual penalty rates and refund rules vary by airline, route, and ticket date, so treat this calculator's output as a rough estimate. Always confirm the exact terms in the fare rules shown at purchase or by contacting the airline directly before assuming a refund amount.
Frequently Asked Questions

It depends on the fare class. Refundable fares carry little or no penalty even close to departure, but Basic Economy tickets can charge a cancellation fee well ahead of time — always check the fare rules before you buy.
