The New 2026 Baggage Rules
Airlines are getting stricter. Especially the "Underseat" rules (bags that must fit under the seat) have been tightened in 2026.
Why FRENKY is your 100% Guarantee
We designed the FRENKY Underseater to be future-proof. Whether you choose the Backpack or the Trolley, both fit perfectly.
- Perfect Dimensions: The "Golden Size" of 40x30x20 cm fits seamlessly with Ryanair, Wizz Air, Norwegian, and Eurowings.
- Squeeze Technology: For strict airlines (KLM, SAS), use the compression straps to bring the bag depth to 15cm.
- No Fines: Travel stress-free in 2026, knowing your bag always flies as a "free item".
Pack 50% more with Vacuum Technology
Complying with rules doesn't mean packing less. The FRENKY Underseater has a built-in vacuum compartment. Pack your clothes, press out the air, and create up to 50% extra space. Enough for 5-7 days of travel.
From plastic bottle to premium travel bag
FRENKY is crafted from recycled PET bottles. The result is ultra-durable, waterproof, and weather-resistant. Travel with a good feeling.
