The short version

If you are flying between European cities on Ryanair, easyJet, Wizz Air or Vueling, every one of them lets you bring a small “personal item” for free, but only some include a larger cabin bag in the basic fare. The exact numbers differ, and so does how strictly each airline measures bags at the gate. Picking a backpack that fits the smallest personal item limit on your itinerary is the simplest way to avoid surprise fees and the risk of being forced to check your bag at the boarding gate.

This guide walks through the current size and weight limits for each of these four airlines, what the personal item versus cabin bag split really means in practice, and how the differences affect your packing choices for a multi-city trip.

Why this matters before you book

A budget flight is only cheap if your bag travels with you in the cabin. Once a bag is “gate checked” or pushed into the hold, you lose time on arrival, you risk damage or loss, and you may have to pay a fee on the spot.

The research below lines up the basic cabin rules from each airline’s own published guidance so you can plan a packing system that survives every leg of a backpacking route, not just the first flight.

Airline Free personal item Cabin bag included in basic fare? Paid cabin bag (if you upgrade) Weight limit Notes from the airline’s own guidance
Ryanair 40 x 30 x 20 cm, must fit under the seat No, basic fare is personal item only 55 x 40 x 20 cm with “Priority & 2 Cabin Bags” 10 kg on the paid cabin bag Bags that do not fit the sizer at the gate are placed in the hold for a fee
easyJet 45 x 36 x 20 cm, must fit under the seat No on the cheapest fare, an “up front” or “extra legroom” seat, or a paid cabin bag upgrade is needed for a larger bag 56 x 45 x 25 cm Up to 15 kg combined easyJet publishes a generous personal item limit, but the larger cabin bag is a paid extra
Wizz Air Published as a small free bag sized to fit under the seat; basic fare is personal item only No, basic fare is personal item only Larger cabin bag available as a paid add-on, typically around 55 x 40 x 23 cm Varies by add-on Rules vary by route, so the published page for your booking is the one to trust
Vueling 40 x 30 x 20 cm, must fit under the seat No on the cheapest “Basic” fare 55 x 40 x 20 cm with “Optima” or higher fare 10 kg on the paid cabin bag Vueling splits fares into Basic, Optima and Family, and only the upper fares include a cabin bag

Always check the page for the airline you are actually flying on the day you book. Limits do change, and a third-party booking site may not match the airline’s current wording.

Ryanair: the strictest sizer at the gate

Ryanair’s basic fare includes exactly one small bag, sized 40 x 30 x 20 cm, that must slide under the seat in front of you. There is no separate cabin bag unless you buy “Priority & 2 Cabin Bags” or hold a Regular or Flexi Plus fare, which then allows a 55 x 40 x 20 cm bag up to 10 kg in the overhead locker.

The Ryanair Help Centre is clear that any bag that does not fit the sizer at the boarding gate can be refused at the gate or, where staff allow it, placed in the hold for a fee. The published descriptions of the gate-check fee in third-party guides cluster around the high double digits in euros or pounds, but the exact figure is set in the airline’s own fee table, which is worth opening before you fly.

Practical consequences for a backpacker:

  • A 40-litre travel backpack will not fit the personal item sizer. It is designed to ride in the overhead locker, which means it only works if you have paid for Priority or hold a higher fare.
  • A daypack around 25 to 30 litres, soft-sided and without a rigid frame, is the most reliable shape for the 40 x 30 x 20 cm box.
  • The personal item limit has no published weight cap, but it has to fit under the seat, so overstuffing it just makes it bulge and fail the sizer.

A simple way to think about Ryanair: pack as if you only have the small bag, then treat Priority as an upgrade you might decide to add later based on how heavy your pack actually turns out to be.

easyJet: bigger personal item, paid cabin bag

easyJet’s personal item limit is more generous than Ryanair’s, at 45 x 36 x 20 cm. That is enough room for a slightly larger daypack or a small messenger bag, and it still has to fit under the seat.

The catch is that the larger 56 x 45 x 25 cm cabin bag is not part of the cheapest fare. You either pick an “up front” or “extra legroom” seat, or pay for a cabin bag as an add-on. The published weight ceiling is up to 15 kg combined across both items, which is among the most generous in Europe for a budget carrier.

What this means in practice:

  • If your route is all easyJet, a 40-litre backpack plus a small daypack can travel together, but only if you have paid for the cabin bag.
  • If you are on the cheapest fare, treat the 45 x 36 x 20 cm personal item as your entire luggage allowance and pack accordingly.
  • The 15 kg combined ceiling is high enough that a single 10 kg backpack is comfortable, leaving a few kilos of headroom in your daypack for a laptop, a jacket and snacks.

The weight ceiling matters more than the dimensions on easyJet, because bags that pass the sizer can still be weighed at the gate.

Wizz Air: personal item by default, cabin bag as an add-on

Wizz Air follows the same logic as Ryanair and Vueling: the cheapest fare is a personal-item-only fare. The small bag is sized to fit under the seat, and a larger cabin bag is sold as a paid add-on, often advertised around 55 x 40 x 23 cm depending on the route and the add-on bundle you pick.

Because Wizz Air sells baggage in bundles rather than as a single fixed product, the exact dimensions and weight can vary by what is in your basket. The practical advice is the same as for Ryanair: confirm the numbers on your booking confirmation before you pack, and measure your bag at home including handles and any external pockets.

For a backpacker mixing Wizz Air with rail segments, the under-seat bag is the one constant, so design your kit around the under-seat limit first, then decide whether to pay for the overhead bag on the flights where it is worth it.

Vueling: fare bundles decide your bag

Vueling splits fares into Basic, Optima and Family. Basic includes the personal item at 40 x 30 x 20 cm; Optima and Family add the larger 55 x 40 x 20 cm cabin bag at 10 kg. The numbers are very close to Ryanair’s, so the same backpack choices apply.

If you are booking Vueling, the choice between Basic and Optima often comes down to one question: will you be able to live out of a 40 x 30 x 20 cm bag for the whole trip, or do you need the overhead bag for a change of clothes, a layer, and a laptop? On a short city break, Basic is fine. On a two-week route through several climates, Optima is usually worth the upgrade.

What this means for a multi-city backpacking route

Most independent travellers flying between European cities mix two or three of these carriers. The simplest rule is to plan around the smallest personal item limit on your itinerary and treat everything else as optional.

Step 1: identify the tightest limit

Scan every booking confirmation and note the personal item size for each flight. On a Ryanair plus Vueling route, both sit at 40 x 30 x 20 cm. On an easyJet segment, the personal item jumps to 45 x 36 x 20 cm. The tightest number is the one your daypack has to satisfy.

Step 2: choose one backpack that fits the under-seat box

Soft-sided daypacks in the 25 to 30 litre range are the easiest fit. They compress enough to slide into the sizer when full, and they have enough internal space for a laptop, a change of clothes, a packable rain layer and a toiletry kit that meets the liquids rule. Hard-shell mini suitcases usually fail the personal item sizer on Ryanair and Vueling because the sizers are rigid boxes and the wheels stick out.

Step 3: decide per leg whether to pay for the cabin bag

If you have a longer route or you are carrying a 40-litre backpack for overhead travel, you will need the cabin bag upgrade on the flights where you cannot go personal-item-only. Compare the upgrade price with the cost of shipping a bag ahead, which is what some travellers do on routes with one or two flights.

Step 4: protect against the gate check

Even when your bag fits, gate agents can still ask you to place it in the hold if the flight is full or overhead space is tight. A few habits reduce the pain:

  • Pack a change of underwear, a phone charger and any medication in your personal item, not in the larger bag, so a forced gate check does not leave you without essentials.
  • Keep bag tags on the outside of the larger bag with your name, phone number and the address of where you are staying that night.
  • Photograph the contents of both bags before you close them. If the hold check delays you, you can describe what was inside without opening the bag at the carousel.

Step 5: weigh before you leave the hostel

Most hostels have a bathroom scale, and many city-centre gyms let you weigh a bag for free if you ask. Ten kilograms feels heavier than people expect once you add a laptop, a charger and a jacket. Weighing before you get to the airport is faster and cheaper than paying overweight fees at the desk.

Common questions

Can I bring a small backpack plus a handbag on every airline? Not automatically. On Ryanair, Wizz Air and Vueling basic fares, the personal item is one bag, not two. If you want to carry a handbag and a daypack, both have to fit inside the single personal item envelope or you need to pay for the cabin bag.

Do airlines weigh the personal item? The personal item has no published weight cap on Ryanair, Vueling or easyJet, but it must fit under the seat and pass the sizer. Staff can still ask you to repack if it is clearly overloaded. On easyJet, the combined weight of both items is capped, so the personal item is weighed indirectly.

What happens if my bag is one centimetre too tall? On Ryanair in particular, gate staff will measure the bag in the sizer. If it does not slide in cleanly, the bag is treated as oversized and can be placed in the hold for a fee. There is no flexibility on this point, so measure at home and leave a small margin.

Is it cheaper to pay for bags at booking or at the airport? Every airline in this guide is cheaper to add bags online at the time of booking than at the airport desk or the gate. The published gap is significant, often a two to three times difference, so decide before you check in.

Are these rules going to change again? EU-level discussions about how essential baggage is displayed in ticket prices were in the news in mid-2026, and individual airlines update their rules throughout the year. Treat the table above as a planning guide, not a contract, and confirm the numbers on the airline’s own page for your booking.

A simple packing rule of thumb

If you remember nothing else, remember this: pick a soft-sided daypack that fits 40 x 30 x 20 cm, weigh it under 10 kg if you plan to upgrade to a cabin bag, and only pay for the overhead bag on the flights where you genuinely need the extra space. The few euros you save on a smaller bag are quickly lost the first time a sizer rejects your pack at the gate.

For the legal and policy specifics that affect your own booking, the airline’s help centre and your booking confirmation are the only sources that count. Independent guides like this one are useful for planning, but they cannot tell you what your particular fare includes on the day you fly.
