8 Hand Luggage Myths That Cost You Money at the Gate

Every travel group chat has one. The friend who swears they've flown Ryanair twenty times with a giant rucksack and nobody's ever said a word. The cousin who "knows a trick" with the sizer. The colleague who insists the rules are changing next month anyway.

Some of this advice is harmless. Some of it will cost you £70 at a boarding gate. Here are the myths we hear most often, and what's actually true.

Myth 1: "They never actually check."

This is the one that gets people. Sometimes they don't check, and that's exactly why the myth survives. But when they do, it's usually at the gate, when you have no time to repack and no alternative but to pay.

Consumer group Which? heard from one member who was charged £70 because the soft lid of their case was half a centimetre too big for the sizer. Half a centimetre. Ryanair has also rolled out updated sizers across its airports, so "it fitted last year" isn't a defence either.

The truth: assume you'll be checked every single time. Then it's never a surprise.

Myth 2: "Wheels and handles don't count."

It depends entirely on the airline, which is what makes this one dangerous. easyJet and Jet2 measure the whole bag, wheels and handles included. Wizz Air excludes them from its trolley measurements, but says they can't add more than 5cm.

The truth: measure everything that sticks out, including side pockets you've filled. If it touches the sizer, it counts.

Myth 3: "If I can squish it in, it's fine."

Soft bags do have some give, and a half-empty backpack will often squeeze in. The problem is a full one. That water bottle in the side pocket, the jumper stuffed in the front, the charger you threw in last: each adds a centimetre or two of bulge, and bulge is what gets caught.

The truth: a bag that's slightly under the limit when packed is safer than one that matches the limit exactly when empty. Choose a bag with a structured shape so it holds its dimensions when full.

Myth 4: "The free under-seat bag has no weight limit, so I can pack anything."

Half true. Ryanair doesn't publish a weight limit for its free 40 × 30 × 20cm bag, but you need to be able to lift it and stow it yourself. Other airlines are stricter: Wizz Air caps its free bag at 10kg and easyJet at 15kg.

The truth: for Ryanair, size is the test. For everyone else, check the weight too. A luggage scale costs less than one gate fee.

Myth 5: "Bundled fares are always better value."

Airlines love a bundle, because bundles bring in more money. When Which? priced a London to Alicante return, picking Ryanair's Basic fare and adding Priority & 2 Cabin Bags yourself was £20 cheaper than the Regular bundle. They even added seat selection and still saved £4.

The truth: start with the cheapest fare and add only the extras you'll actually use. Compare the final total, not the headline.

Myth 6: "Budget airlines are always cheapest."

Only if you travel with nothing but a small bag. Add a cabin bag and the maths can flip. Which? found a London to Malaga return in July cost £146.28 on British Airways with a cabin bag included. The same trip with bags came to £222.98 on Wizz Air and £243.59 on Ryanair.

The truth: either travel with just the free under-seat bag and enjoy the low fare, or compare the full cost against airlines that include a cabin bag. The worst value is paying budget-airline bag fees on a trip where BA or Jet2 would have been cheaper.

Myth 7: "New EU rules mean cabin bags are free now."

You'll see this headline every few months. The EU has agreed a minimum free personal item of 40 × 30 × 15cm for flights to and from the EU, but according to Which?, it won't come into force until 2027. It also may not cover UK airlines flying out of the UK.

The truth: today's rules are the ones printed on the airline's website today. Pack for those.

Myth 8: "Your personal item has to be a handbag or a laptop case."

Plenty of people still picture the free "personal item" as a small handbag. In reality, most airlines' definitions explicitly include a small backpack, and Ryanair's free bag is now big enough for a short trip if you pack well.

The truth: a well-designed 40 × 30 × 20cm backpack holds around 24 litres. That's enough for a long weekend, and with careful packing, more.

The one rule that beats every myth

Almost every gate fee comes from the same mistake: finding out the rules at the airport instead of at home. So before your next trip:

1. Look up your airline's exact sizes for your exact fare.
2. Pack your bag, then measure and weigh it, fully loaded.
3. Leave a centimetre of breathing room.

We designed the Vackpack around the 40 × 30 × 20cm limit for this reason: it's a backpack built to pass the sizer on Ryanair and Wizz Air, rather than one that hopes to.
