HK Express carry-on: fare categories and 7 kg combined

Ultra Lite and Essential include one personal item up to 40×25×20 cm and 7 kg. Lite and Max include that item plus one main cabin bag up to 56×36×23 cm. With two items, 7 kg is their combined weight, not a separate limit for each. Adding airport shopping does not create another allowance.

Check the fare, not just the bag size

Ultra Lite and Essential passengers can purchase a main cabin bag; the total remains 7 kg. Essential includes one 20 kg checked bag, while Max includes one 32 kg checked bag. Ultra Lite and Lite do not include ordinary checked baggage. A checked allowance does not replace the missing main cabin entitlement. Bookings made before 8 May 2024 may retain earlier conditions.

Purchase channel and gate outcome

The official fee table updated 29 March 2026 lists a main cabin bag for Ultra Lite/Essential per passenger and flight segment: HKD 130 through Manage My Booking, 180 during online check-in, 300 through Customer Connect, or 350 at the airport check-in counter. Check the current quote and available service before paying.

Excess baggage discovered at the boarding gate is a different outcome: HKD 800 per piece, checked into the hold, with a 32 kg maximum. Unused checked allowance does not offset this gate charge. The calculator keeps fees unknown because one generic online/gate choice cannot distinguish a cabin purchase from compulsory checking. A compliant cabin bag may also be checked free if cabin storage is full.

Liquids, power banks and the checker

Liquids normally use containers up to 100 ml in one clear resealable bag up to 1 litre; baby food/milk and liquid medicine have conditions. Check transfer screening. The dedicated power-bank rule permits at most two, up to 100 Wh, in the cabin and protected individually. Do not store them overhead, use or charge them onboard. A separate 100–160 Wh device row is not automatic permission for a larger power bank.

Check your bag. The basic-fare result checks personal-item entitlement; Lite/Max or a purchased main bag requires the appropriate selection. The tool checks one bag, so weigh both together yourself. Measure the packed outside shape; wheel/handle inclusion is not explicitly established in the reviewed HK Express text. Confirm the booking and operating airline rather than transferring Cathay Pacific allowances.
