Improving surface access is a commercial and environmental challenge facing airports across the globe, write ICFs Angus Reid-Kay and Rob Rushmer.

To focus on airlines and the development of an airports route network would provide only a partial view of that airports connectivity. This is because surface access matters, and failure to meet demand on the ground can hamper growth.

On the surface

Airports know and understand this, but worldwide they face an emerging 21st century challenge: how to balance their service, commercial, cultural and sustainability objectives.

The aviation industry tends to think of the passengers journey as being from airport X to airport Y. Indeed, we spend most of our time monitoring the activity of airlines and modelling the movement of aircraft, passengers and cargo around our network of regional and global airports.

Arguably, we spend less time focusing on the passengers surface journey to and from the airport. In most cases, that infrastructure is outside of the airports control whereas the air journey is fully within it so a focus on air connectivity is understandable, but it is not forgivable.

Whether going on holiday, visiting family and friends or a business trip, every passengers journey begins and ends at home. And, although journeys vary and might involve a taxi, hire car or public transport trip, they inevitably include a trip to the airport or train and/or bus station, potentially weighed down with luggage, and likely stress.

The surface journey at both ends features large in the passengers planning. Who has not been more stressed worrying about an on-time arrival at the airport to catch the flight, than an on-time departure once safely through security?

Airports are somewhat unusual businesses in that the customer is not entirely theirs.  At the airport, the passenger interacts with the airline, the airlines agents, the airports retailers, or the states border authorities. Outside the airport, the passenger interacts with the states transport network.

Therefore, surface connections at the airport itself most notably the final mile (set down, car parking or train or bus station interface) present one of the few passenger touchpoints that the airport can fully control.

It is therefore very important for the airport to get it right: to gift the passenger a good experience and memory of the airport. It is also a commercially important touchpoint, and in some regions the most important for the airport.

North America in particular is exposed to the commercial impact of a reduction in private car related income with around 40% of airports non-aeronautical income derived from the use of a private car, but its geography makes it more challenging to put in place public transport alternatives.

In contrast, Hong Kong has a natural geographical advantage promoting the use of public transport.

However, in a time of increasing focus on climate change, airports worldwide are, through preference or legislation, having to manage a modal shift away from private to public transport means of accessing the airport. This can clearly create commercial tension.

From an environmental perspective, there is a clear order of preference for public transport access as the most sustainable, long-term solution, through parking a private car, to drop off by taxi, which has the advantage of likely also taking a different passenger from the airport, to private drop-off, being the least sustainable necessitating two vehicle journeys for every one passenger journey.


In geographies that historically have prioritised the private vehicle, either through practical necessity or as a perception of personal aspiration, this trend requires that the passengers journey through the public transport network, likely carrying luggage on and off trains and buses, is simplified and eased.

How, therefore, have airports tackled this challenge? The world is perhaps too full of mixed success stories. Debatably, the most successful examples are in Asia-Pacific where certain states have either natural geographical advantages to the widespread uptake of public transport (Hong Kong, for example), but, possibly, they have also avoided the US and European historical legacy of seeing the private car as an aspiration.

The most recent example of the addition of a new rail link to an airport is the Soekarno-Hatta Airport rail link in Jakarta, Indonesia, where road access to the airport has been notoriously difficult.

The new rail link, which opened in late 2017, offers a 55-minute journey to central Jakarta compared to an unpredictable two hours that a car journey may take.

And the government is now contemplating extending the high-speed rail network to serve the airport.

Less successful has been the city of Torontos efforts to encourage passengers onto the Union Pearson Express (UP Express), linking Union Station in downtown Toronto to Pearson International Airport.

Following lukewarm interest from the private sector, it was eventually built by the government and, despite high customer satisfaction, low patronage has allegedly led to significant tax payer subsidy.

On the other hand, the newly opened and high-performing rail link at Taoyuan International Airport (Taipei) is on track to wash away any negative connotations relating to the long roll-out of the project. After all, the express service reaches downtown Taipei in 35 minutes and offers check-in and baggage check services at stations along the route.

Maybe the UP Express will attract passengers in time and perhaps the delayed opening of the Taoyuan rail link will be forgiven, but the greatest success story must be the Hong Kong Airport Express. The challenges of excavating through mountains, navigating the Victoria harbour and linking it with the airport on reclaimed land were overcome by the advanced planning of the government majority owned MTR Corporation.

On top of the seamless connectivity the rail link adds to the Hong Kong mass transit railways (MTR) network, the Airport Express offers a higher service standard than commuter lines, as well as check-in at Hong Kong and Kowloon stations.

Although it must be noted that despite the comfort, reliability and convenience of the Airport Express, as well as Hong Kongs natural geographical advantage, the rail link still only captures just over 20% of the market to and from the airport, perhaps demonstrating the difficulty of satisfying the wide-ranging needs of individuals connecting to an airport.

Nevertheless, the success of Hong Kong has lead the MTR Corporation to announce that it is contemplating backing new rail links into Heathrow in the UK. The UK government has recently commenced a process of engagement to encourage private sector involvement to develop new rail links into Heathrow.

Global experience offers successful and unsuccessful examples of public transport links to airports. Cultural expectations play a part, as do the challenges or advantages of the particular geographies.

It is, however, likely that as global initiatives in the 21st century increasingly prioritise impacts to climate change, all airports will become more involved with their surface access and the use of public transport.

In so doing they can take greater control over a key customer touchpoint, but must balance that with the commercial needs of an evolving range of non-aeronautical incomes.
