London Heathrow power outage's impact on Finnair flights on 21-22 March 2025

London Heathrow Airport experienced a significant power outage on 21 March. Unfortunately we had to cancel all our flights on 21 March. The power outage at London Heathrow Airport is mostly over and operations are gradually restarting. From 22MAR onwards Finnair operates to and from LHR normally, delays may be possible. 

The situation is closely monitored, and any new information will be updated in this news.

If there are changes to the customer's flight, they will be contacted personally via SMS and/or email. To receive Finnair’s messages, please make sure that customers’ contact information on bookings is up to date.

Finnair has proposed a new connection to the customer and automatically updated the ticket.  

In case the new schedule is not suitable for the customer, the SSR OTHS INVOL element in the booking permits one further free involuntary change and/or cancellation as per the below guidelines.

For bookings made via NDC: same policy applies, and for booking handling contact our Agent Help Desk. The smoothest option for contacting is by clicking on the chat icon at the bottom right corner of the page (select NDC Support) for the change or cancellation.
