What to know about AIRDO carry-on rules

• Among the 31 verified airlines from East Asia, AIRDO has the 2nd largest cabin bag allowance; the strictest is 9 Air (20×30×40 cm).
• In its standard fare, AIRDO applies exactly the same cabin bag, personal item and weight figures as ANA (All Nippon Airways) and Solaseed Air, so a bag packed for one of them also passes on AIRDO.
• In volume terms the AIRDO cabin bag reaches about 55 L; 18 of the 170 airlines with published sides allow a bigger box.
• AIRDO ranks 50th of 189 verified airlines by cabin bag size in the standard fare: its 115 cm (45.3 in) total is bigger than 19% of them.
• Compared with the 31 airlines from East Asia on this site, whose cabin bags average 112.9 cm (44.5 in) in total, AIRDO 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 0.9 cm (0.3 in) too big on the length when measured against AIRDO's 55×40×25 cm.
• Tested against AIRDO's 55×40×25 cm limit, a typical European cabin case of 55 × 40 × 20 cm (21.7 × 15.7 × 7.9 in) matches the limit exactly (0 cm margin) on 3 sides.
• Of 177 verified airlines with a published cabin weight limit, 9 allow more than AIRDO's 10 kg (22 lb) for both bags together and 129 allow less.
• The 10 kg (22 lb) limit on every fare of AIRDO covers the personal item and the cabin bag together, not each bag.
• Besides the 55×40×25 cm sides, AIRDO caps the sum of length, width and height at 115 cm.

AIRDO personal item: what fits under the seat

• AIRDO's fare also includes a cabin bag, so the personal item comes on top of it.
• Filled as a box, AIRDO's 40×30×20 cm personal item holds about 24 litres, above 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), AIRDO allows 90 cm, more than 70% of them.
• AIRDO gives the personal item no weight of its own: it shares the 10 kg (22 lb) total with the cabin bag.
• By volume, the 40×30×20 cm personal item on AIRDO is 44% of the 55×40×25 cm cabin bag: about 24 L against 55 L.
• A soft 40 × 30 × 20 cm (15.7 × 11.8 × 7.9 in) under-seat bag matches the limit exactly (0 cm margin) against AIRDO's 40×30×20 cm personal item limit.
• With 90 cm in total, the AIRDO personal item is bigger than 58 and smaller than 27 of the 108 verified airlines that publish a personal item size.
• Other personal item limits at the same airport: ANA (All Nippon Airways) at HND (40×30×20 cm) and Solaseed Air at HND (40×30×20 cm), against 40×30×20 cm on AIRDO.

Our notes on AIRDO

AIRDO counts everything you carry on board against one weight: 10 kg per person, personal effects included. Within that, you may bring one piece of carry-on baggage and one personal effect.

The two items have their own sizes. The carry-on may total 115 cm, which AIRDO spells out as no more than 55 × 40 × 25 cm. The personal effect is limited to 40 × 30 × 20 cm and must be stowed under the seat in front of you, so a small backpack that is deeper than 20 cm belongs in the overhead bin as your main piece. On flights between Sapporo New Chitose and Tokyo Haneda, the weight of the personal effect is not separate: a 3 kg laptop bag leaves 7 kg for the main piece.
