Train or Plane? How to Optimize Your Travel Policy

Many corporate travel policies are specific about what employees can spend. This leaves gaps that are open to (subjective) interpretation. Mode of transport, for example. If travel is inland, should employees fly or take the train?

The question is more important than you might think. Flying is fast, but it can be expensive and is carbon-heavy. What’s more, some people prefer travelling by train. It’s more affordable, has more space, and can be more relaxing than flying. 

Your business needs a travel policy that addresses all these issues and more. For example, carbon reporting is getting stricter, the cost of fossil fuels is going only one way, and different types of travel take a toll on employees. You couldn’t pay some to set foot on a plane, while others have nightmares if they’re expected to board a train. 

Your policy needs to be clear about modes of transportation, including defaults, exceptions, booking setups, and flexible options.

Here’s how to approach it.

When Should Rail Rule the Day?

Clarity is key. Employees must know what their options are and when they are available. 

For example: 

• UK routes under four to four and a half hours: These routes, like London to Edinburgh, London to Manchester, and most major UK city pairs, should default to the train. 
• Door-to-door time is what matters: Flying is not always the fastest mode of transport. London to Edinburgh by train typically takes 4.5 to 5 hours door-to-door, while flying often takes 4 to 6 hours once airport transfers and security are included.
• Key Eurostar routes are clear rail defaults: Hop on the train and London to Paris takes 2 hours 16 minutes city centre to city centre, London to Brussels is under two hours, and London to Amsterdam hovers around four hours.
• Flying wins on longer European routes: Once train travel time hits around six hours, flying becomes more efficient.

Ensure the default is clear, but allow for flexibility. However, make it clear that flexible options are the exception and that the justification is reasonable. 

Four Factors Supporting Rail Travel

Travel managers often know rail makes sense on shorter routes, but flying has an allure, or even status, for some employees. If you feel you need to back up your water-tight default policy, you can always leverage the below.

• Cost: Train tickets booked in advance are frequently cheaper than flights once airport transfers, baggage fees, and parking are factored in. A managed travel programme enforces advanced booking for rail just as it does for flights.
• Sustainability: For companies with Scope 3 reporting obligations, shifting to rail on shorter routes immediately reduces business travel emissions. According to Rail Delivery Group data, a London to Edinburgh train journey produces 12.5kg CO2e per passenger, compared to 165kg CO2e by plane.
• Employee well-being: Navigating airports is a primary source of stress for business travellers. Train travel removes the airport entirely. No security queues, no baggage restrictions, no transfer at the other end. Employees arrive ready to work.
• Productivity: Railway carriages are designed for employees to work during a long train journey. This simply isn’t possible on a short-haul flight.

When these factors are weighed together, the case for rail travel on shorter routes is almost beyond dispute. 

Genuine Flexibility Without Making the Exception the Rule

The trick is to maintain fairness between budget considerations and traveller comfort. Flexibility provisions make the difference between an employee-friendly policy and one focussed entirely on pounds and pence. 

• Set route-level defaults, not blanket rules: Flexibility enables employees to fly on a covered route if they have a documented reason, an early morning meeting, a same-day return on a tight schedule, or a connecting flight onward.
• Make rail booking frictionless: Ensure all bookings, no matter the mode of transport, are on a unified platform. Otherwise, employees default to whatever is easiest. 
• Account for individual circumstances: Some employees have mobility needs that make long train journeys uncomfortable. Other mobility needs make flights uncomfortable. Some employees are based in cities with poor rail connections. Flexibility should allow for these exceptions without making them the norm.
• Review exceptions periodically: Be prepared to adapt when necessary. For example, if most employees on a covered route opt out, the default may need adjustment, or the booking experience may need improvement.

You want to design a business travel policy that optimises the right mode of transport at the right time. Then, trusting employees not to exploit the exceptions.

A Clearer Policy Makes for a Calmer Traveller

One of the easiest ways to manage evolving corporate travel requirements is to choose a default mode of transport, especially within certain circumstances. For example, train travel to inland venues that are four hours away.

It’s easy because it doesn’t require much effort, technology, capital investment, or a policy overhaul. All you need are clear default transport options, a unified booking platform, and genuine flexibility for the cases where rail doesn’t work. 

Other than satisfied employees, you’ll also benefit from reduced costs, improved sustainability numbers, and business travel that is noticeably less stressful.
