Hong Kong Airport to the City: Airport Express, Bus or Taxi

Which side of the harbour you land for

Hong Kong International Airport sits on Chek Lap Kok off Lantau Island, on the Kowloon and New Territories side of Victoria Harbour, so the first thing to settle is whether your address is on Hong Kong Island. Everything that ends on the Island crosses the harbour; everything that ends in Kowloon does not. That single fact changes the bus route you want and adds a fixed amount to a taxi meter.

The airport has no ordinary MTR station. The Airport Express is the only railway into the terminal, and it is priced as a premium service with its own fare table rather than on the distance-based fares used by the rest of the network. The nearest ordinary-fare station is Tung Chung, one bus stop away, and that gap is where most of the money in this decision sits.

Airport Express and its free shuttle

The Airport Express is the fastest published option into the city and the most expensive per head. Trains depart at approximately 15-minute intervals from 05:54 to 00:48 daily and reach Central in what the Airport Authority's Airport Express page calls "just 24 minutes" (checked 16 September 2026). Free porter service is available at all Airport Express stations.

Fares from the airport, as published by the Airport Authority, differ depending on whether you buy a Smart Ticket or tap an Octopus card.

Two extras are what actually justify the fare for some travellers. A free shuttle bus runs from Kowloon and Hong Kong stations to most major hotels and transport interchanges, which removes the short taxi hop at the end that undercuts cheaper options. And free In-town Check-in is offered at Hong Kong and Kowloon stations, where the same page states passengers can check in between 120 minutes and one full day ahead of their scheduled flight departure time.

Cityflyer A-routes by district

Citybus Cityflyer A-routes are double-deckers with luggage racks in the lower saloon, and they are the option that puts you closest to a hotel door for a fraction of the train fare. Citybus describes the lower deck as having spacious luggage racks and a CCTV system so passengers can watch their bags, and advertises a 50 per cent discount on a same-day return paid with the same Octopus card, on its Cityflyer route page (checked 16 September 2026). Children under 12 and seniors aged 65 or over pay half fare.

Four routes cover the districts most visitors stay in. Fares below are the adult fare from the airport.

Journey times are long by the standards of the train. Citybus lists roughly 80 minutes for the A11 to North Point, about 78 minutes for the A21 to Hung Hom and about 73 minutes for the A29 to Tseung Kwan O, all checked on 16 September 2026. The A21 is the densest service, leaving the airport every 10 to 15 minutes for most of the day; the A29 runs every 30 minutes and does not start until 08:40.

The S1 and the Tung Chung Line

The S1 shuttle is the cheapest published way out of the airport, and it is the only option here that needs a change of vehicle. Citybus prices the S1 circular between Tung Chung Station and the passenger terminals at HKD 3.50 for adults and HKD 1.80 for children, with an approximate journey time of 35 minutes for the full loop and departures every five to ten minutes for most of the day (checked 16 September 2026). At the airport it picks up at the Terminal 1 (South) stop on Cheong Tat Road.

At Tung Chung you change to the ordinary Tung Chung Line, which is priced on the normal distance-based scale rather than the Airport Express one. MTR's published station-to-station fare file gives Tung Chung to Hong Kong Station as HKD 24.30 on Octopus or HKD 28.00 on a single-journey ticket, and Tung Chung to Kowloon as HKD 18.70 on Octopus (file last modified 2 April 2026, read 16 September 2026).

This route is worth avoiding if you are travelling alone with two large cases and no lift-free plan, or arriving after the Tung Chung Line has stopped for the night. It is worth taking if you are two or more people on a budget, or if your hotel is anywhere along the Tung Chung Line itself.

Red taxis and the doubled harbour toll

Red urban taxis run on a published meter, not an airport flat fare, and the fare table is the document that governs what you pay. The Transport Department's taxi fare table, effective 14 July 2024 and checked on 16 September 2026, sets an urban-taxi flagfall of HKD 29 for the first 2 kilometres or any part thereof, then HKD 2.10 for every subsequent 200 metres or every minute of waiting, until the chargeable amount reaches HKD 102.50, after which each increment drops to HKD 1.40.

On top of the meter, the same table sets these additions:

• Every piece of baggage carried in the boot, or carried in the passenger compartment with total dimensions over 140 cm: HKD 6. Baby prams count. Wheelchairs and crutches carried by disabled passengers are free.
• Every animal or bird: HKD 5.
• Every hiring arranged through telephone booking: HKD 5.
• Cross-Harbour Tunnel, Eastern Harbour Crossing or Western Harbour Crossing: HKD 25 as the amount of the toll, plus HKD 25 as a return toll.

The return toll is the part that surprises people. The Transport Department states it is not payable by the passenger if the hiring begins from a cross-harbour taxi stand, or if the final destination is not on the opposite side of the harbour. A taxi from the airport rank to an address on Hong Kong Island meets neither exemption, so budget HKD 50 of harbour toll on top of a long meter; a taxi to Kowloon crosses nothing and pays neither. Notably, the urban-taxi surcharge list contains no Lantau Link entry at all.

Night buses after the last train

The N-series overnight buses are the scheduled public transport link into the city once the Airport Express and the Tung Chung Line have stopped for the night. Citybus runs the N21 from the airport to Tsim Sha Tsui Star Ferry at HKD 23.0 for adults, leaving the Ground Transportation Centre from 00:20 and roughly every 20 minutes until 04:40, with an approximate journey time of 80 minutes (checked 16 September 2026).

For Hong Kong Island, the N11 runs to Central at the Macau Ferry terminal at HKD 31.0 for adults, departing the airport at half-hourly fixed times from 00:50 to 04:50, taking about 75 minutes (checked 16 September 2026). Both routes use Octopus section fares, which means you must tap both when boarding and when alighting or you will be charged to the end of the line.

A taxi remains available around the clock, and the Transport Department's urban-taxi table sets out no night surcharge. What the meter does do is keep climbing with distance, so a 4 am ride to the far side of the Island is the most expensive transfer in this guide.

Before you leave the arrivals hall

Decide your route before you reach the Ground Transportation Centre, because the Airport Express counter, the bus stops and the Taxi Station are in different directions and doubling back with a trolley is the slowest part of any of these options. If you want the cheap route, look for the S1 at the Terminal 1 (South) stop on Cheong Tat Road rather than among the A-route bays.

This guide prices four Citybus Cityflyer routes, the S1, two N-series night buses and the red-taxi meter. It does not price the A-routes to the New Territories run by Long Win Bus, the E-series routes, the residents' coaches, or the cross-boundary coach services to the Chinese mainland and Macau. It also does not cover the Airport Express round-trip and group fares, or the free shuttle-bus route map, because MTR's website was returning a maintenance notice rather than those pages when this article was checked on 16 September 2026.
