Diagnose your problem
Which Wizz Air Bag Do You Actually Need?
Free underseat vs WIZZ Priority trolley — and expandable bags that must fly compressed.
Problem
Free underseat 40×30×20 / 10 kg
No WIZZ Priority ticket; need the strict underseat allowance with weight limit
Recommendation
Soft backpack default — Aerolite B0GD247PJR or BAGZY B0CN65SPNF. Weigh packed bag — Wizz states 10 kg on free carry-on
Products
Problem
WIZZ Priority trolley 55×40×23 / 10 kg
You purchased WIZZ Priority and need overhead trolley size
Recommendation
Aerolite expandable Priority class B01JZAONW6 — do not buy 55×40×23 expecting free underseat acceptance. Expand only within Priority limit
Products
Problem
Expandable bags
Your bag has a zip-out expansion section for extra packing at home
Recommendation
Fly at 20 cm depth for free Wizz allowance — VANKEV B0F1YKWRY6 only if expansion stays within 40×30×20. Expanded depth can fail sizers
Products
Problem
Wizz vs Ryanair vs easyJet
Cross-airline packing when you fly more than one UK budget carrier
Recommendation
Wizz free size matches Ryanair 40×30×20; Wizz adds explicit 10 kg. easyJet free small bag is larger — see easyJet spoke. A 40×30×20 bag fits inside easyJet allowance
Products
Problem
Measure packed
Include pockets, strap bulk and compression — do not force the sizer
Recommendation
Measure at home at 40×30×20 cm packed. Soft shells flex slightly when not overfilled — do not overstuff zips

Wizz Air cabin bag safety & compliance
Do not force an overfilled bag into a Wizz sizer — broken zips and torn fabric are common, and gate staff may refuse the bag. Wizz limits, enforcement and fees change; check the airline fees page before travel. We do not quote guaranteed fee amounts. Measure your packed bag at home at 40×30×20 cm including pockets and strap bulk. Weigh packed bags — Wizz states 10 kg on free carry-on. We have not physically tested these bags at Wizz gates.
Research Methodology
How We Chose These Products
Editorial Wizz Air-focused research — not live gate sizer testing or laboratory dimension verification.
We prioritise Amazon UK listings explicitly naming Wizz Air with verified 40×30×20 cm titles — avoiding Cabin Max Metz ASINs that currently resolve to 40×20×25 variants on amazon.co.uk. We compare stated dimensions against Wizz’s published free underseat and Priority limits (September 2026 snapshot) and weight soft vs expandable vs wheeled practicality. We never invent gate fees or claim guaranteed airline acceptance.
