Quick answer: Every easyJet passenger gets one free small cabin bag that must fit under the seat in front, with a larger overhead bag available on certain fares and seat types. Allowances change, so check easyJet's own baggage page before you fly and pack to the smaller size.

What this guide covers

easyJet's baggage rules have changed more than once in recent years, and the numbers get repeated online long after they stop being true.

So the first and most useful thing to say is this: check easyJet's own baggage page before you fly. What follows is about how to pack the bag, which does not change.

The two bags, in principle

Every passenger gets a free small cabin bag that has to fit under the seat in front of you. That under-seat space is the real constraint, and it is not very deep.

A larger cabin bag for the overhead locker comes with certain fares, seat types and memberships, and can be added to a booking. Whichever you end up with, packing cubes are what make the smaller one viable. Whether it is worth paying for is a genuine question rather than an obvious yes - for trips up to about four nights, most people do not need it.

What actually fits in the free bag

Less than the dimensions suggest, because the shape wastes space. Realistically:

  • Two small packing cubes – one clothes, one everything else
  • A clear liquids bag
  • A charger case, a book, and whatever you need in the seat

That is three or four days of clothing if you choose things that mix and wear the bulkiest layer to the airport. The same discipline as the Ryanair free bag, which is the strictest free allowance in the UK.

Packing so it passes the sizer

Budget airlines measure, and a bag that nearly fits is a bag you pay for at the gate. Two things decide it:

Use a soft bag. A soft-sided bag packed in squared blocks will compress the last centimetre into a frame. A hard shell simply will not - it is either the right size or it is not.

Square off the load. Loose clothing bulges at the corners, which is exactly where a sizer catches. Compression cubes remove the air and give the bag back the shape it was designed to have – there are numbers in the compression guide.

Is the bigger bag worth paying for?

Up to about four nights, usually not - the free bag genuinely does it if you pack to a capsule. Beyond a week, or if you are travelling with children, or in winter when coats dominate, it often is.

Work it out against a hold bag too. On some routes the difference is small enough that checked luggage makes more sense than fighting an overhead locker. The carry-on guide works through the capsule that makes the free bag viable.

The short version

  • Every easyJet passenger gets a free small cabin bag that must fit under the seat in front.
  • A larger overhead bag depends on your fare, seat or membership – check before you fly, allowances change.
  • The free bag realistically holds two small cubes, a liquids bag and your in-seat things.
  • Use a soft-sided bag: it compresses into a sizer where a hard shell either fits or does not.
  • Up to about four nights the free bag is usually enough; beyond a week, paying for more often is not optional.

Frequently asked questions

What size is the free easyJet cabin bag?

It is the small bag that must fit under the seat in front of you, and easyJet has changed the exact dimensions more than once. Always check easyJet's current baggage page before flying rather than relying on a figure quoted online.

Can I take a backpack as my easyJet cabin bag?

Yes, as long as it fits the allowance and goes under the seat. A soft backpack is often the better choice precisely because it squashes into a sizer, where a rigid case cannot give at all.

How many days can I pack into the free easyJet bag?

Three or four comfortably, if you pack a capsule where everything mixes and wear your bulkiest layer to the airport. A week is possible but tight, and usually not worth the effort in winter.

Will packing cubes help my bag fit the easyJet sizer?

Compression cubes will, because they remove trapped air and stop clothing bulging at the corners, which is where a sizer catches. Standard cubes organise the bag but do not make it smaller.

Is it cheaper to pay for a bigger cabin bag or check a bag?

It depends on the route and how far ahead you book, and the gap is often smaller than people assume. Price both at the time of booking - adding baggage at the airport is always the most expensive option.
