With the Finnair Flight Change Policy , it is easy to change your travel plans. You can update your flight using "Manage Booking" online. The airline lets you change your flight for free in the first 24 hours after you book. After this time, the cost depends on your ticket. Business and Flex fares usually let you make changes without a fee. If you have an Economy Light ticket, you may need to pay more. If Finnair delays, reschedules, or cancels your flight, you can rebook for free. This set of rules helps travelers feel sure about their trips. Always read your fare rules to avoid any extra costs and to have the best travel experience.
