Frequently Asked Questions (Finnair)
How does the 15 cm Squeeze Hack work for Finnair?
The FRENKY is 20 cm deep by default. By using the vacuum compartment for your clothes and tightening the four side buckles, you reduce the depth to 15 cm. This meets Finnair's 'Small Bag' requirements perfectly.
Is the bag really free on Finnair?
Yes. As long as you stay within 40x30x15 cm (using the straps) and your bag fits under the seat in front of you, it counts as your free personal item.
How do I claim the free toiletry bag?
It's easy: 1. Add an Underseater to your cart. 2. Also add the luxury toiletry bag to your cart. 3. Enter code FINNAIR2026 at check-out. The price of the toiletry bag will be automatically deducted from your total!
