Some airlines allow passengers – particularly in business class – to carry a second bag into the cabin. These are often referred to as ‘handbags’ or ‘laptop bags’. Again, there is no definitive size limit – however, several European airlines suggest a maximum of 40 cm x 30 cm x 15 cm (16 inches x 12 inches x 6 inches). All PLIQO bags comply with this limit when normally packed.
