What is Wizz Air's free bag allowance?

Wizz Air's free allowance is one small personal item measuring no more than 40×30×20 cm. This must fit entirely under the seat in front of you. There is no weight limit stated for this bag, but it must fit in the dimensions without forcing.

How much does a Wizz Air cabin bag cost?

Prices vary by route, demand, and how early you book. Adding a cabin bag (55×40×23 cm) at the time of booking is typically cheaper than adding it later. At the gate, it becomes a checked bag fee, which is significantly more expensive — often €50–90.

Do I need Priority Boarding to use the overhead bin on Wizz Air?

Yes. Wizz Air only guarantees overhead bin access for passengers with a cabin bag entitlement (included in Plus, Wizzflex, or purchased as an add-on). Without it, your free personal item must go under the seat. If overhead space is available, crew may allow it, but this is not guaranteed.

What is Wizz Air Plus and does it include a cabin bag?

Wizz Air Plus is a subscription service that includes a cabin bag allowance on every flight, plus other benefits like free flight changes and priority boarding. For frequent Wizz Air travelers, it can work out cheaper than paying per-flight bag fees.

How strict is Wizz Air about bag sizes?

Wizz Air is among the strictest airlines in Europe for bag enforcement. Physical bag sizers are commonly placed at boarding gates. Bags that do not fit the sizer are refused boarding and must be checked at the gate for a significant fee. Do not try to squeeze an oversized bag through.

Wizz Air Cabin Bag Rules: Size, Fees & Tips (2026)

Wizz Air has one of the most complex cabin baggage systems in Europe. What looks like a simple budget airline allowance is actually a tiered structure with strict size enforcement, additional fees for overhead bin access, and a subscription product that bundles it all together. Getting it wrong at the gate can cost you more than the flight itself. This guide explains exactly how it works.

Wizz Air's Two-Bag Structure

Wizz Air separates its cabin baggage into two distinct categories:

1. The Free Personal Item (40×30×20 cm)

Every Wizz Air passenger — regardless of fare type — is entitled to bring one small personal item on board free of charge. The maximum dimensions are 40 × 30 × 20 cm (length × width × depth).

This bag must fit under the seat in front of you. It does not go in the overhead bin. Common options that fit within this allowance include:

A small backpack or daypack
A large handbag
A laptop bag or slim briefcase
A 20-litre backpack (if the dimensions comply)

There is no stated weight limit for this free bag, but it must fit within the dimensions without bulging.

2. The Cabin Bag (55×40×23 cm)

The larger cabin bag — which goes in the overhead bin — is not included in the base fare. It must be purchased separately as an add-on, or is included with specific fare types:

Wizz Air Plus (subscription) — includes cabin bag on all flights
Wizzflex fare — includes a cabin bag
Paid add-on — purchased during or after booking

The cabin bag dimensions are 55 × 40 × 23 cm and it comes with a 10 kg weight limit. This is one of the smaller overhead bin allowances in Europe compared to airlines like easyJet (56 × 45 × 25 cm).

Why Priority Boarding Matters

On Wizz Air, only passengers who have a cabin bag entitlement (purchased or included in their fare) are permitted to board in the priority group and use the overhead bins. Passengers without this entitlement board last and are expected to keep their free personal item under the seat.

In practice, this means overhead bin space fills up with priority passengers' bags before general boarding begins. If you board without a cabin bag entitlement and try to place your personal item overhead, crew may ask you to move it.

How Fees Have Changed

Wizz Air has repeatedly increased its cabin bag fees in recent years, particularly since 2022. Key changes include:

Late add-on fees: Adding a cabin bag after booking costs more than at checkout
Gate fees: If you arrive at the gate with an oversized bag or a bag you haven't paid for, it becomes a checked bag — the fee is substantially higher and varies by route, but regularly exceeds €50
Dynamic pricing: Bag fees vary by route, season, and demand, similar to how flight prices work

The gap between booking-time prices and gate prices has widened significantly. The clear takeaway: add your cabin bag at the time of booking if you need it.

Enforcement: What to Expect at the Airport

Wizz Air is consistently ranked among the strictest European airlines for bag enforcement. Here's what that looks like in practice:

Bag Sizers at the Gate

Physical metal sizer frames are frequently placed at Wizz Air boarding gates, particularly at their main bases in Budapest, Bucharest, Vienna, and London Luton. Passengers may be asked to place their bag in the sizer before boarding.

If your bag does not fit the sizer — including with pockets, wheels, and handles — it will not be allowed on board as a cabin bag. You'll be asked to check it and pay the gate fee.

What Gets Flagged

Soft-sided bags that are overpacked and distorted beyond their frame
Bags in the overhead bin that belong to passengers without a cabin bag entitlement
Bags that technically meet size limits but clearly exceed the 10 kg weight limit (less commonly weighed, but possible)

What Doesn't Usually Get Flagged

A laptop bag or small backpack clearly fitting the personal item dimensions
Small handbags well within the free allowance
Coats and jackets carried over the arm (not counted as a bag)

How to Avoid Wizz Air Bag Fees

Option 1: Pack Within the Free 40×30×20 cm Allowance

The most cost-effective approach is to travel with only a bag that fits under the seat. A well-designed 20-litre backpack in the right proportions holds 3–5 days of clothing if packed efficiently with packing cubes.

Bags specifically designed for Wizz Air's free allowance are widely available and clearly marketed with those dimensions. Look for ones that are rigid enough to hold their shape but have compression straps to reduce volume when partially full.

Option 2: Buy the Cabin Bag at Booking

If you need more space, add the cabin bag when you book — not later. The price is lowest at the point of initial checkout and increases as you approach the travel date.

Option 3: Consider Wizz Air Plus

If you fly Wizz Air more than three or four times a year, the Wizz Air Plus subscription may cover the cost of bag fees across multiple flights. It also includes free flight changes, which adds further value for uncertain itineraries.

Option 4: Use Wizzflex When Available

On some routes, Wizz Air offers a Wizzflex fare that bundles the cabin bag, priority boarding, and free cancellation. If the price difference versus the base fare is smaller than the bag fee alone, Wizzflex can be better value even if you don't need the other inclusions.

Comparing Wizz Air to Ryanair and easyJet

Feature	Wizz Air	Ryanair	easyJet
Free bag	40×30×20 cm	40×20×25 cm	45×36×20 cm
Cabin bag size	55×40×23 cm	55×40×20 cm	56×45×25 cm
Cabin bag included	Plus/Wizzflex	Priority only	Flexi/Plus
Weight limit	10 kg	10 kg	No limit
Enforcement	Very strict	Very strict	Moderate

EasyJet's free allowance is meaningfully larger and the paid cabin bag has more generous dimensions. Ryanair's system is similarly strict to Wizz Air but with a slightly different free bag dimension.

The Bottom Line

Wizz Air's bag rules reward passengers who understand the system. The free 40×30×20 cm personal item is workable for short trips with efficient packing. If you need overhead bin space, adding the cabin bag at booking time — or subscribing to Wizz Air Plus — is substantially cheaper than any alternative. Never arrive at the gate with a bag you haven't paid for. The enforcement is real, the fees are steep, and the sizers are out.
