Default is Economy Light/Classic/Flex. Economy Superlight includes only a small bag. All cabin items share the selected class total; the checker evaluates one bag and does not sum your bags. Measure the fully packed external dimensions.

The source does not say whether wheels and handles are included, so measure the full external size to be safe.

Baggage fees

No reliable fixed price is listed here. Check your booking for the cost of adding a bag; an unlisted price does not mean it is free.

Official baggage policy
How to use this policy

Check cabin bag dimensions, weight and personal-item limits separately. A bag has to pass every published limit at once; being under the length and width limit does not help if the depth, weight, or fare-specific allowance is tighter.

Editorial signal only. Measure the packed bag and verify the operating carrier's rule.

Finnair liquids policy

Ordinary liquids: containers up to 100 ml in one resealable transparent 1-litre bag. Helsinki Airport departures allow 2 litres total, still in containers up to 100 ml; Helsinki transfers and other Finavia airports use the 1-litre bag rule. Essential medicines and baby food have screening exceptions. Confirm every departure and transfer airport.

Family & Infants

Infant (under 2)

An infant without a reserved seat has no separate cabin-baggage allowance; bring baby food and milk needed for the journey. Finnair states a 10% adult-fare infant ticket without a seat.

Stroller

A foldable pushchair and safety seat travel free, including Superlight and Light. A cabin-size pushchair normally counts as the main cabin bag; on Superlight it may travel free in addition to the small bag. Larger pushchairs travel in the hold.

Car seat

A child under 7 with a reserved seat may use a compliant child seat, subject to Finnair safety requirements. Child seats are not permitted in A350/A330 Business Class.

Children's allowance

A child with their own seat has the cabin allowance of their ticket type.
