• Among the 31 verified airlines from East Asia, China Southern Airlines has the 2nd largest cabin bag allowance; the strictest is 9 Air (20×30×40 cm).
• In its standard fare, China Southern Airlines applies exactly the same cabin bag, personal item and weight figures as Chair Airlines, China Eastern Airlines, Tunisair and Xiamen Airlines, so a bag packed for one of them also passes on China Southern Airlines.

• 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 China Southern Airlines' 55×40×20 cm.
• On China Southern Airlines, a typical European cabin case of 55 × 40 × 20 cm (21.7 × 15.7 × 7.9 in) matches the limit exactly (0 cm margin); the limit is 55×40×20 cm.
• 8 kg (17.6 lb) for the cabin bag: 84 of the 177 airlines with a published limit are stricter than China Southern Airlines, 53 are more generous.
• Exceptions noted on the official China Southern Airlines page: China Southern First and Business passengers may bring two carry-on pieces of up to 8 kg each. (official text: “Domestic Flight First Class 2pc 8kg The length, width and height of each carry-on shall not exceed: 55 * 40 * 20 cm (or 22 * 16 * 8 inches) Business Class Premium Economy Class 1pc Economy Class International/Regional Flight First Class 2pc Business Class Premium Economy Class 1pc Economy Class”)
