How Strict Is Finnair With Carry-on?
Finnair takes its carry-on rules seriously and enforces them to ensure a smooth experience for all passengers.
That means they’re likely to check both the weight and size of your carry-on bag.
If your carry-on doesn’t meet their size requirements, you may need to check it in, which could cause some extra fees.
So, it’s best to make sure that your bag’s dimensions are within the limits before heading to the airport.
Finnair Approved Cabin Bag
Your carry-on allowance depends on your ticket type and travel class.
Here is what you’re allowed to bring on board:
