Flexible flights are those which allow for changes or cancellations after the purchase has been made. By purchasing a flexible flight, also known as flexi flights or open tickets, travelers are able to change travel dates or even cancel last-minute for no fee or a smaller fee than with regular airline tickets.

The primary difference between a Flexi Fare and a Regular (Standard) Fare in 2026 is the degree of financial risk you take when your plans change. A Regular Fare is typically the lowest price point; it allows for travel on a specific date and time but usually carries heavy penalties for changes (often $150–$250) and is completely non-refundable if you cancel.

It allows for unlimited date and time changes without a change fee (though you must still pay the difference in ticket price) and is often fully refundable back to your original payment method if you cancel. Flexi Fares also frequently include "perks" that Regular fares do not, such as free seat selection, a checked bag, and priority boarding. For business travelers or those with uncertain schedules in 2026, the Flexi Fare is a form of insurance, whereas the Regular Fare is the "bet" that you will definitely make your flight as originally scheduled.
