Booked a cheap flight, and now you’re squinting at the baggage page trying to work out what counts as a free cabin bag? Yeah, you’re not alone there. Every UK airline runs its own slightly different rules, and getting it wrong at the gate turns a bargain fare into a genuinely expensive mistake real fast. Let’s just go through what each one actually allows, so you can pack once and stop thinking about it.
What Actually Counts as a Cabin Bag
Two categories usually floating around here, worth knowing upfront. A small personal item that fits under the seat in front of you. And a bigger cabin bag that goes in the overhead locker. Airlines almost always give you the small one free. The bigger one’s where fees start creeping in.
Trips people up constantly, this bit. Book a “basic” fare thinking you’ve sorted a proper suitcase, then find out at check-in you’ve only paid for the tiny underseat bag. Worth checking your ticket type before packing, not after learned that one the hard way more than once.
Ryanair Cabin Bag Rules
Ryanair’s free allowance is genuinely the tightest going. Every ticket includes one small bag up to 40 x 30 x 20cm. No weight limit on it at least, small mercy. Want a bigger bag for the locker? Priority Boarding gets you a 10kg bag up to 55 x 40 x 20cm.
Here’s the bit that catches people out though Ryanair staff use an actual metal sizer at the gate, measured including wheels and handles, not just the main body. A bag that “looks about right” often isn’t, and that gap catches more people than you’d think. No Priority, doesn’t fit? Fee up to £70. Rough way to kick off a holiday, that.
easyJet Cabin Bag Allowance
easyJet’s usually the more generous one. Often where people switch to after a bad Ryanair gate experience happens a lot, honestly. Free underseat bag’s 45 x 36 x 20cm, up to 15kg. Noticeably bigger than Ryanair’s free allowance. For plenty of short trips, genuinely enough on its own.
Need more room? Add a larger cabin bag up to 56 x 45 x 25cm for the locker, though that usually needs an upgraded fare or Plus membership rather than just buying it outright.
British Airways and Jet2
Both include more as standard, part of why tickets run a bit pricier upfront. British Airways typically allows two bags free smaller one around 40 x 30 x 15cm, plus a larger cabin bag up to 56 x 45 x 25cm, each up to 23kg. Jet2 gives a 10kg cabin bag up to 56 x 45 x 25cm alongside a small underseat bag, included as standard.
Fly these two more than the budget lot? You’ll notice it feels a lot less stressful. Less gate-side measuring anxiety, basically, and that’s worth something on its own.
One Cabin Bag That Works Everywhere
Fly a mix of airlines? Buying a different bag for each gets expensive and impractical, fast nobody wants three suitcases cluttering the hallway. Good news though, there’s a rough sweet spot. A bag no bigger than 40 x 30 x 15cm satisfies the free allowance across most UK carriers, Ryanair included.
Soft-sided over hard-shell helps more than people expect, too. A rucksack or soft holdall can squish slightly into a tight sizer frame. A rigid suitcase just fits, or it doesn’t no middle ground there. Bouncing between budget airlines a lot? That flexibility’s worth factoring in when buying.

Packing Tips to Dodge Gate Fees
Few habits make a real difference. Measure your own bag before travelling, wheels and handles included, rather than trusting some “cabin approved” tag manufacturers measure just the shell, and that’s not how gate staff do it.
Wearing your bulkiest coat or boots onto the plane instead of packing them still works, especially near the weight limit rather than the size one. Travelling with an infant? Most airlines, Ryanair too, allow a separate baby bag and baby equipment free, no impact on your normal allowance at all.
A New EU Rule’s Coming, Just Not Yet
Change on the horizon, worth flagging. The EU’s ruled that airlines flying to or from EU countries must offer a free standard cabin bag of at least 40 x 30 x 15cm. Sounds like good news, and eventually will be but it doesn’t kick in until 2027, and might not even apply to non-EU carriers flying from the UK. For now, current airline-by-airline rules still stand. Don’t assume anything’s changed yet.
Final Thought
Cabin bag rules vary way more than people expect, and that gap’s exactly where gate fees quietly rack up. Check your specific airline first. Measure your bag properly instead of guessing. Fly often? Worth investing in one bag sized for the strictest allowance you’re likely to hit. Saves money. Saves a fair bit of gate-side stress too, honestly.
