Quick Answer
British Airways offers the most generous free cabin allowance (two bags, up to 23kg each), followed by Jet2 (two bags included, 10kg cap). easyJet, Wizz Air, and Ryanair only include a small under-seat bag for free; a full overhead cabin bag costs extra on all three. A single 40×30×20cm bag fits every airline’s free allowance simultaneously.
While budget carriers compete on lower lead-in fares, add-on fees for overhead luggage often erode those initial savings. Choosing a bag that matches universal under-seat dimensions guarantees you avoid gate penalties regardless of the airline you fly.
The Sunset Weekly Connection Reality: British Airways’ liberal hand luggage rules remain a significant advantage over budget alternatives. When factoring in the cost of adding overhead bags on low-cost carriers, full-service airlines often provide better total value alongside a stress-free boarding experience.
BOOK ON BRITISH AIRWAYSVerified Allowance Comparison
We checked these figures directly against each airline’s own published policy in August 2026, rather than repeating them from other guides.
| Airline | Free Personal Item | Free/Included Overhead Bag | Weight Limit | Key Detail |
|---|---|---|---|---|
| British Airways | 40×30×15cm | 56×45×25cm, included on all fares | 23kg combined for both bags | No per-bag weight limit stated; you must lift the bag into the locker unaided |
| Jet2 | 40×30×20cm, no published weight limit | 56×45×25cm, included on all fares | 10kg (cabin bag only) | Jet2 can still gate-check the bag into the hold on full flights unless you add Guaranteed Cabin Luggage |
| easyJet | 45×36×20cm, 15kg | 56×45×25cm, paid add-on (or included with FLEXI fare/easyJet Plus) | 15kg on both bags | You can no longer buy the large bag at the airport, online only, or a £48 gate fee applies if it doesn’t fit under the seat |
| Wizz Air | 40×30×20cm, 10kg (excludes handles/wheels; wheels may add up to 5cm) | 55×40×23cm, requires WIZZ Priority | 10kg per bag | Wizz Air measures both bags the same way, excluding wheels/handles but capping the extra at 5cm |
| Ryanair | 40×30×20cm, no weight limit | 55×40×20cm, requires Priority & 2 Cabin Bags | 10kg (overhead bag only) | Ryanair increased the personal item size from 40×20×25cm on 4 September 2025 |
British Airways’ weight allowance is 23kg combined across both bags, not per bag. Its personal item measures 40×30×15cm, smaller than some comparison guides state.
Why Ryanair Changed Its Free Bag Size in 2025
The size increase
On 4 September 2025, Ryanair increased its free personal bag from 40×20×25cm to 40×30×20cm, roughly 20% more volume. This wasn’t a goodwill gesture. The European Parliament adopted a position in January 2026, building on a June 2025 EU member-state agreement, pushing to standardize a minimum free personal-item size across European carriers. Ryanair’s new size deliberately exceeds the EU’s proposed 40×30×15cm minimum, positioning the airline ahead of a regulation that isn’t law yet.
The stricter enforcement that followed
There’s a second, less publicized change worth knowing if you fly Ryanair regularly. In November 2025, Ryanair reportedly raised the staff incentive for catching non-compliant bags from €1.50 to €2.50 per bag. The airline also removed the previous monthly cap on that incentive. If you’ve flown Ryanair before 2025 and never had your bag checked, don’t assume that’s still the norm. That assumption is now genuinely out of date.
The One Bag That Fits All Five Airlines
If you only want to own a single cabin bag rather than packing differently for every airline, target 40×30×20cm. This size falls within the free personal-item allowance on Jet2, Wizz Air, and Ryanair. It also fits comfortably inside British Airways’ and easyJet’s larger free allowances.
If you’re willing to pay for the larger overhead allowance on the budget carriers (Priority on Ryanair, WIZZ Priority, easyJet’s large bag add-on), a 55×40×20cm bag clears every airline’s paid overhead limit. It also fits BA’s and Jet2’s included allowance, giving you meaningfully more packing capacity across the board.
What doesn’t work universally: a 56×45×25cm case, BA and Jet2’s included size, is too large for Ryanair’s and Wizz Air’s overhead allowances, even when you add Priority.
What Real Travelers Actually Report at the Gate
The airlines’ published policies are one thing. What actually happens at the gate is another, and genuine traveler accounts from r/travel and r/Shoestring paint a more textured picture than any policy page.
Enforcement depends on who’s checking, not just which airline
Multiple travelers independently describe the same pattern: enforcement varies by staff, by airport, and by how full the flight is, rather than airlines applying it uniformly every time. One detailed account notes that major hub airports (Heathrow, Charles de Gaulle, Milan Malpensa) tend to enforce less strictly than secondary “low-cost” airports (Luton, Beauvais, Bergamo). The same account describes Scandinavian airports showing more consistent rule-following than some Southern or Eastern European ones. Ground staff are often third-party contractors, one traveler specifically named Swissport, and enforcement can shift noticeably day to day even on the same route.
Traveler experiences match the documented Ryanair change
One traveler describes Ryanair staff forcing them to check a 34-litre bag in May, the first time this happened in 15 years of flying the airline. They directly attribute it to a genuine crackdown, consistent with the November 2025 enforcement-incentive change above. Other accounts from earlier in 2025 describe years of flying with oversized bags, with staff never stopping them. This is a real before-and-after split, and it lines up with the documented timeline rather than contradicting it.
Bag shape and material matter as much as exact dimensions
Several travelers report that soft, compressible backpacks squeeze into gate sizers more easily than rigid suitcases, even when both are technically the same size. One account describes successfully fitting a 40-litre bag into the sizer. They removed bulky items first and compressed the bag by hand. A rigid case at the same declared size might not offer that same flexibility.
Paying online in advance is consistently cheaper than risking the gate
This is the most repeated, most practical theme across both threads. One traveler describes a genuinely bad outcome. They booked what looked like a £20 flight, then staff stopped them at the gate and charged roughly £50 for a checked bag and a seat, turning a cheap fare into a considerably more expensive one. The advance-purchase price for the same allowance is typically a fraction of that.
Weight enforcement is the least consistent rule of all
Some travelers report flying dozens of times without staff ever weighing their cabin bag. Others describe a different experience: staff weighed their bag, found a modest overage (12kg against an 8kg limit, in one account), and waved them through anyway. Airlines with a published weight limit (Jet2, easyJet, Wizz Air) can and do enforce it. Real-world accounts suggest this happens far less consistently than size checks at the gate sizer itself.

The Practical Takeaway
Pack to the smallest common denominator (40×30×20cm) if you want one bag that works everywhere without paying extra anywhere. Measure your actual bag, including wheels and handles, since several airlines explicitly count them. If you’re flying Ryanair specifically, treat “I’ve never been checked before” as outdated advice. It predates September and November 2025, and it’s no longer a reliable guide to what happens now.
FAQs
Comparing the Airlines
1. Which airline has the most generous free cabin bag allowance?
British Airways, with two included bags (a 56×45×25cm cabin bag and a 40×30×15cm personal item) and a combined 23kg weight allowance across both, no per-bag limit stated.
2. Is Jet2’s free allowance genuinely as good as British Airways’?
Close. Jet2 includes the same two-bag structure and identical cabin bag dimensions (56×45×25cm), but caps the cabin bag at 10kg, whereas BA states no per-bag weight limit, only that you must lift it unaided.
3. Which airline has the biggest free under-seat bag?
easyJet, at 45×36×20cm with a 15kg limit, notably larger than the 40×30×20cm free allowance on Jet2, Wizz Air, and Ryanair.
4. What size cabin bag fits every one of these five airlines’ free allowance?
40×30×20cm fits within the free personal-item allowance on Jet2, Wizz Air, and Ryanair, and comfortably inside the larger free allowances on British Airways and easyJet.
Ryanair Specifically
5. Did Ryanair’s free bag size actually change recently?
Yes. On 4 September 2025, Ryanair increased its free personal bag from 40×20×25cm to 40×30×20cm, roughly 20% more volume, positioning itself ahead of a pending EU minimum-size proposal.
6. Is Ryanair stricter about cabin bags now than it used to be?
Genuine traveler reports and a documented policy change both point that way. In November 2025, Ryanair reportedly increased its staff incentive for catching non-compliant bags and removed the previous monthly cap. Multiple travelers report a noticeable enforcement shift around that time.
7. Does Ryanair weigh the free personal bag?
Ryanair states no weight limit for the free personal bag. Only the 55×40×20cm Priority overhead bag carries a published 10kg limit.
Practical Packing
8. Do handles and wheels count toward the size limit?
It varies. British Airways, Jet2, easyJet, and Ryanair measure the full bag including wheels and handles. Wizz Air excludes them from the base measurement but caps how far wheels can protrude (up to 5cm extra).
9. Is it cheaper to pay for a larger bag online or at the gate?
Online, by a significant margin on every airline covered here. Real traveler accounts describe gate fees roughly doubling or tripling the cost of pre-booking the same allowance.
10. Can I buy easyJet’s large cabin bag at the airport?
No. easyJet removed the option to purchase the large cabin bag at the airport. You must add it online in advance, or pay a £48 fee at the gate if an unbooked bag doesn’t fit under the seat.
