What to know about HK Express carry-on rules

• From HKG, HK Express mainly connects Hong Kong SAR China with Japan, South Korea, Taiwan, Thailand and Vietnam.
• HK Express' Ultra Lite & Essential fare has no free cabin bag, while 189 of the 220 verified airlines we track include one with a published size.
• Tested against HK Express' 56×36×23 cm limit, a standard US carry-on of 22 × 14 × 9 in (55.9 × 35.6 × 22.9 cm) fits, but with only 0.1 cm (0 in) to spare on the length.
• A typical European cabin case of 55 × 40 × 20 cm (21.7 × 15.7 × 7.9 in) is 4 cm (1.6 in) too big on the width when measured against HK Express' 56×36×23 cm.
• Across its 2 fares, HK Express changes the rules: 1 of the 2 includes a cabin bag; on Ultra Lite & Essential the cabin bag is a paid extra.
• HK Express counts both bags in one 7 kg total on the Ultra Lite & Essential fare, so a heavy personal item reduces what the cabin bag may weigh.

HK Express personal item: what fits under the seat

• Ultra Lite & Essential is the HK Express fare where nothing but the personal item travels free in the cabin.
• Filled as a box, HK Express' 40×25×20 cm personal item holds about 20 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), HK Express allows 85 cm, more than 20% of them.
• HK Express sets a separate 7 kg (15.4 lb) limit for the personal item; only 31 of the 220 verified airlines publish a weight for this bag.
• HK Express' personal item (40×25×20 cm, about 20 L) holds 43% of the volume of its cabin bag (about 46.4 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 width against HK Express' 40×25×20 cm personal item limit.
• With 85 cm in total, the HK Express personal item is bigger than 17 and smaller than 54 of the 108 verified airlines that publish a personal item size.
• Other personal item limits at the same airport: Hong Kong Airlines at HKG (40×30×15 cm), against 40×25×20 cm on HK Express.
