• Among the 31 verified airlines from East Asia, Jeju Air has the 2nd largest cabin bag allowance; the strictest is 9 Air (20×30×40 cm).
• In volume terms the Jeju Air cabin bag reaches about 44 L; 116 of the 170 airlines with published sides allow a bigger box.

• Compared with the 31 airlines from East Asia on this site, whose cabin bags average 112.9 cm (44.5 in) in total, Jeju Air allows 2.1 cm (0.8 in) more.
• A standard US carry-on of 22 × 14 × 9 in (55.9 × 35.6 × 22.9 cm) is 2.9 cm (1.1 in) too big on the depth (and 1 other limit) when measured against Jeju Air's 40×20×55 cm.
• A typical European cabin case of 55 × 40 × 20 cm (21.7 × 15.7 × 7.9 in) matches the limit exactly (0 cm margin) when measured against Jeju Air's 40×20×55 cm.

• On Jeju Air (every fare), 10 kg (22 lb) is a combined allowance: add the weight of the personal item to the cabin bag.
• Besides the 40×20×55 cm sides, Jeju Air caps the sum of length, width and height at 115 cm.

Jeju Air personal item: what fits under the seat

• Jeju Air's fare also includes a cabin bag, so the personal item comes on top of it.
• Filled as a box, Jeju Air's 40×30×15 cm personal item holds about 18 litres, right at the median of 18 L across the 105 airlines that publish three personal item sides.
• Against the 11 airlines from East Asia that publish a personal item size (average 87.3 cm in total), Jeju Air allows 85 cm, more than 20% of them.
• Jeju Air gives the personal item no weight of its own: it shares the 10 kg (22 lb) total with the cabin bag.
• By volume, the 40×30×15 cm personal item on Jeju Air is 41% of the 40×20×55 cm cabin bag: about 18 L against 44 L.
• A soft 40 × 30 × 20 cm (15.7 × 11.8 × 7.9 in) under-seat bag is 5 cm (2 in) too big on the depth against Jeju Air's 40×30×15 cm personal item limit.
• With 85 cm in total, the Jeju Air personal item is bigger than 17 and smaller than 54 of the 108 verified airlines that publish a personal item size.
