Bags that fit Aer Lingus’s free small bag (40 × 30 × 20 cm)
Aer Lingus’s free small bag on its cheapest fare must fit 40 × 30 × 20 cm. These 6 bags are listed by their own makers at or under that size, wheels and handles included. Sizes checked on each maker’s page on 26 Oct 2026.
4 of them are exactly the limit, with no room to spare. A soft bag that bulges when full can fail the sizer, so don’t overstuff it.

We list a bag only when its maker’s own page gives one clear size, and we don’t show prices because they change. Some maker sites may not open from every country.
Look out: bigger than they seem
Their makers present these as under-seat or cabin bags of this kind, but the makers’ own measurements are bigger than this size. Check the numbers, not the label.
