If you don't turn up for a flight, you will either be rebooked on another flight, charged a cancellation fee or will lose the entire value of your ticket. Which of these happen will depend on the reasons you are missing the flight, the type of flight/ticket you have booked and whether or not you inform the airline.

If you "no-show" for a flight in 2026, you generally won't be charged an additional penalty fee on your credit card, but you will likely suffer a total loss of the ticket value. Most airlines operate under a "No-Show Policy" which dictates that if you are not on the plane by departure, the entire itinerary—including any return or connecting flights—is automatically canceled without a refund. For "Basic Economy" tickets, the money is typically forfeited entirely. For standard "Main Cabin" or higher fares, some airlines might allow you to apply the remaining value (minus a significant change fee) toward a future flight, but only if you cancel before the plane takes off. Furthermore, if you booked with frequent flyer miles, a no-show often results in the loss of those miles unless you pay a "redeposit fee." It is always financially smarter to cancel or change your flight at least 10 minutes before departure via the airline's app to retain some value as a "Future Flight Credit" rather than simply not showing up.
