HK Express is a pure low-cost carrier — Hong Kong’s only one — and it flies nothing but short and medium-haul Asia (Japan, Korea, Taiwan, Southeast Asia, mainland China), all under about five hours. That uniformity matters for your bag: there is no long-haul exception here. The cheapest fare, Ultra Lite, gets you exactly one small personal item up to 7 kg that fits under the seat (40 x 25 x 20 cm) — no overhead cabin bag, no checked bag, on every single route in the network.
Since the May 2024 four-tier overhaul, the fares split cleanly: Ultra Lite and Lite include zero checked baggage; Essential bundles 20 kg checked, and Max bundles 32 kg checked plus a standard seat. The quirk worth knowing: Essential gives you a checked bag but no overhead cabin bag (just the personal item), while Lite gives you the overhead cabin bag but no checked bag. Pick the wrong one and you pay twice.

What you actually get on a cheap fare
On a cheap HK Express deal fare you are almost certainly on Ultra Lite — and that means a single under-seat bag and nothing else. No overhead cabin bag, no checked bag. If you want a roller in the overhead bin you either pay the cabin-bag add-on or step up to a Lite fare; if you need a checked bag you add 20 kg or buy an Essential. The smart move on most trips is to compare the all-in: Ultra Lite + prepaid 20 kg versus simply booking Essential — Essential frequently lands cheaper than fare-plus-add-on, and it locks the bag in.
Budget realistically: a prepaid checked bag varies by route and how early you buy, but it is a real chunk on top of a HK$300–600 promo fare, and the gate penalty is brutal — HKD 800 per piece for anything that doesn’t fit the cabin rules. Buy baggage online before you check in; never let it become a counter or gate transaction.
Oversize, sports & special items
Oversized or heavy items (anything over 32 kg per piece or 158 cm total) must be booked as Special Baggage with an extra fee — this is the route for golf clubs, skis, surfboards, bicycles and musical instruments. There is no free sports/instrument allowance; it all comes out of your purchased checked allowance plus any oversize charge, so pre-arrange it rather than gambling at the airport.
The big 2024–2026 change is the move from two fares to four (Ultra Lite, Lite, Essential, Max), introduced 8 May 2024 and still current. HK Express has also rolled out an add-on cabin-bag option so Ultra Lite and Essential passengers can buy a single overhead bag without upgrading the whole fare — useful, but still cheaper bought in advance than at the gate.
Frequently asked questions
Does the cheapest HK Express fare include a checked bag?
No. Ultra Lite (the cheapest fare) includes only one under-seat personal item up to 7 kg — no overhead cabin bag and no checked bag. This is the same on every HK Express route.
Which HK Express fares include a checked bag?
Only Essential (20 kg) and Max (32 kg). Ultra Lite and Lite include no checked baggage; you must buy it separately.
Can I bring a normal carry-on roller bag on Ultra Lite?
Not for free. Ultra Lite includes only a small personal item (40 x 25 x 20 cm). To bring an overhead cabin bag (56 x 36 x 23 cm) you must add the cabin-bag option for a fee or book a Lite or Max fare.
What is the carry-on size and weight limit?
The cabin bag limit is 56 x 36 x 23 cm, and the personal item is 40 x 25 x 20 cm. Combined cabin bag plus personal item must not exceed 7 kg total.
How much is a checked bag on HK Express?
Prepaid checked allowance is sold in increments (roughly 20–40 kg) in HKD, and the price varies by route, date and booking channel. It is cheapest bought online in advance; overweight is HKD 120 per kg.
What happens if my bag is too big at the gate?
Excess cabin baggage or an oversized personal item is charged a gate fee of HKD 800 per piece. Always buy baggage online before check-in to avoid this.
Is the baggage allowance different on long-haul HK Express flights?
HK Express has no long-haul flights — its entire network is short and medium-haul Asia (under about five hours). Baggage rules are identical on every route; there is no region-based checked-bag inclusion.
Should I book Ultra Lite plus a bag, or Essential?
Compare the all-in price. Ultra Lite plus a prepaid 20 kg bag is often more expensive than simply booking Essential, which includes 20 kg. Essential also guarantees the bag is on the booking.
