Frequently Asked Questions (Wizz Air)

Is this bag free to bring on Wizz Air flights?

Yes. As long as you stay within 40x30x20 cm and your bag fits under the seat in front of you, it is guaranteed free as your personal item.

Do they measure handles and straps?

Yes. Always measure the external dimensions: including handles, straps, pockets, and any protrusions. FRENKY is designed to fit the 40x30x20 cm sizer including these parts.

Do I need an upgrade for extra cabin bags?

If you want to bring a larger overhead cabin bag, Wizz Air requires a "WIZZ Priority" upgrade. By using an underseat-only item like FRENKY, you fly the cheapest way possible.

Does the vacuum system make the bag wider?

No, the opposite. You remove air from your clothes, not the bag. Make sure to pull the side compression straps tight afterward to keep the bag "flat" for the sizer.

What about warranty and shipping?

You receive a 1-year warranty on the vacuum compartment. Shipping is free on orders over €99 (DE, BE, FR & NL), and you have a 14-day return policy.
