Read this before you buy it as a cabin bag

At 25 × 20 × 40cm it is well inside the 55 × 40 × 20cm cabin allowance most airlines publish. It also sits inside Ryanair’s free under-seat bag size of 40 × 30 × 20cm (checked on Ryanair’s help centre, 16 September 2026), but exactly on the 40cm height and the 20cm depth — which means it fits that sizer only if you do not overpack it. A bulging bag will not go in. Check your airline before you fly.
