Do I need a passport or visa to fly from London to Helsinki?
You will need to bring along your valid UK passport to allow you to enter Finland but you do not currently require a visa if you plan to visit Finland as a tourist for less than 90 days. Something to keep in mind, however, is that any visits to other Schengen countries during the 180 days before you travel to Finland will count towards those 90 days. If you wish to stay in Finland for longer than this time period Finnish government entry requirements must be met and a visa may be required. We recommend taking a look at the Finnish government website for further information and advice.
