    Hong Kong — Service Centre WhatsApp

There is no dedicated disability line — all assistance goes through the regional Service Centre numbers above, which are open 09:00–20:00 daily only, so a 48-hour request cannot be placed overnight. The Service Centre is also the channel for telling the airline the type of battery-powered wheelchair and battery you are bringing.

Powered wheelchairs & batteries

The part that goes wrong. Battery chemistry and watt-hours decide whether your chair flies, and the rules differ depending on whether the battery can be removed.

Powered chairs accepted
Yes

Battery-powered wheelchairs are accepted as free checked baggage: 'all non-foldable manual and battery-powered wheelchairs can only be accepted as check-in baggage (free-of-charge)'. You must notify the Service Centre at least 48 h ahead of the type of chair and battery, and bring the user manual, the tools to disassemble and reassemble the chair, and UN 38.3 documentation for a lithium-ion battery. 'Battery-powered wheelchairs or mobility aids must fulfil the IATA DGR dangerous goods requirements.'

Lithium-ion batteries
Yes

Lithium-ion wheelchairs are carried. 'For lithium-ion battery-powered wheelchair, documentation to prove the battery meets the United Nations (UN) test requirements as specified in the UN Manual of Tests and Criteria, Part III Section 38.3' must be brought to the airport.

Watt-hour cap — battery stays in the chair
Not published

Not published. Greater Bay Airlines' 300 Wh figure is tied to the case where the battery has to come out: 'If the mobility aid does not provide adequate protection to the battery: Battery must be removed ... Battery must not exceed 300 Wh.' It publishes no watt-hour ceiling for a battery that stays installed in an adequately protective chair. ICAO/IATA defaults apply — see global rules.

Watt-hour cap — battery removed into the cabin
300 Wh

'If the mobility aid does not provide adequate protection to the battery: Battery must be removed according to the manufacturer's instructions; Battery must not exceed 300 Wh; Battery terminals must be protected from short circuit (e.g., by insulating or taping over exposed terminals); Removed battery must be protected from damage (e.g., by placing each battery in a protective pouch), and must be carried in the cabin.'

Watt-hour cap — spare battery
300 Wh

'A maximum of one spare battery not exceeding 300 Wh or two spare batteries not exceeding 160 Wh each may be carried. Spare batteries must be carried in the cabin.'

Baggage — Special Baggage: Mobility Devices, and Important Information Regarding Lithium Batteries (opens in a new tab) · read 2026-07-29

Spare batteries permittedmaximum number under any published configuration
2

One spare of up to 300 Wh, or two spare batteries not exceeding 160 Wh each — the maximum permitted count is therefore 2, at the lower watt-hour rating. Spare batteries must be carried in the cabin. For non-spillable wet, dry-cell or gel batteries the limit is one spare per passenger.

Battery must be removed
Conditional

Removal is required only where the chair itself does not protect the battery: 'If the mobility aid does not provide adequate protection to the battery: Battery must be removed according to the manufacturer's instructions', must not exceed 300 Wh, must have its terminals insulated, must be placed in a protective pouch and must travel in the cabin. Greater Bay Airlines does not say who decides whether the protection is adequate.

Non-spillable batteriesgel, AGM, sealed lead-acid, dry cell
Yes

'Non-spillable wet battery, dry-cell battery or gel-type battery: Measures must be taken to prevent short circuit (e.g., by covering exposed terminals) and unintentional activation.

Not published

Not published for the return leg. On departure, 'You may use your own wheelchair to the departure boarding gate and aircraft door, if possible within the airport facilities', and the attendant assists 'to the boarding gate or aircraft door' — but Greater Bay Airlines never says whether the chair is returned at the aircraft door on arrival or only in the baggage hall.

Wheelchair passengers may not be seated in emergency exit rows. Hearing-impaired passengers are offered wheelchair assistance only if they ask for it themselves, and airport staff assess whether a lone hearing-impaired passenger needs a personal/safety assistant.

Worth knowing

Greater Bay Airlines publishes a genuinely detailed mobility-device policy on its baggage page — better than most carriers of its size — covering spillable, non-spillable and lithium-ion batteries, a 300 Wh removed-battery cap, one 300 Wh or two 160 Wh spares in the cabin, terminal protection, UN 38.3 documentation and the tools you must bring. Three things it does NOT publish, and which matter: no watt-hour limit for a battery that stays installed in an adequately protective chair (the 300 Wh figure only bites when the chair must give the battery up); no maximum weight or dimensions for a chair, and no hold-door figures; and nothing about the chair being returned at the aircraft door on arrival. Two things a wheelchair user should read carefully before booking. First, Greater Bay Airlines states flatly that its flights 'will not accept passengers with medical conditions', and that crew 'is not qualified to provide any medical or health-related care'. Second, anyone who needs help moving between their seat and the lavatory must buy a seat for a personal assistant — there is no on-board aisle chair described anywhere, and no accessible lavatory is claimed. Damage liability is the bare Montreal Convention 1,519 SDR with no mobility-aid carve-out, so a power chair is substantially under-covered. Practical note: the Service Centre hotlines are open 09:00–20:00 local only, and 48 hours' notice is required for the wheelchair service, the personal assistant booking and the battery declaration alike. A human should confirm with the airline (a) who judges whether a chair 'provides adequate protection' to its battery, since that single judgement decides whether a 400 Wh installed battery flies at all, and (b) whether a folding manual chair may be taken into the cabin — the wording 'all non-foldable manual and battery-powered wheelchairs can only be accepted as check-in baggage' implies folding chairs are treated differently, but the site never says so.
