Is Private Travel Becoming a Rational Economic Choice, Not Just a Luxury?

Gary Becker's 1965 paper, A Theory of the Allocation of Time, argued that the cost of time should be considered alongside the cost of market goods, treating time as an important economic resource. Becker's idea was that each minute of flying time represents an opportunity cost of earning income through time spent working. Becker's framing leads us to pose the following question regarding UK private aviation today: as the market continues to grow and diversify, are we starting to view the cost of chartering an aeroplane from a perspective beyond its luxury image (i.e., as a trade-off for the expense of lost time)?

The Value of Time, Not Just the Ticket

The UK's own transport appraisal guidance already treats time this way. The Department for Transport values business travel time savings using the traveller's gross wage rate plus non-wage labour costs, on the logic that an hour saved in transit is an hour returned to productive work. For a senior executive whose time commands a high hourly rate, the opportunity cost of a delayed connection or a half-day lost to airport transfers can exceed the price premium of chartering outright. This mirrors utility maximisation: a rational consumer weighs total satisfaction against the full cost of a decision, not just the sticker price.

The Numbers Behind the Shift

There is a clear shift in how people use private jets and how they are likely to use them in the future. For example, between 2025 and 2026, it is projected that the global private jet charter market will increase from $24.12 billion to $27.38 billion, representing a CAGR of 13.5%. Europe is projected to experience 9.2% year-on-year growth from a base of just over 1 million trips. In addition, the profiles of buyers are changing. VistaJet reports that 47% of its new customers are now under 45, a marked shift from a market historically dominated by older, ultra-wealthy individuals. Rising demand for membership and on-demand charter access is quickly surpassing fractional ownership as the fastest-growing method of accessing private jets, indicating that high-net-worth charter clients are looking for flexibility rather than having to pay the associated fixed costs of owning a private jet. 

Why Income Elasticity Still Matters

Income elasticity of demand for chartered flights remains high: demand rises sharply with income and wealth and falls away quickly when income growth slows, a pattern that is characteristic of a luxury good rather than a necessity. Charter flights are therefore considered luxury items and not necessities. Charter flight demand is primarily due to an increase in the number of wealthy individuals and not because of a general trend in what the average traveller thinks about their time. Because of this, Becker’s framework will not typically apply to most people, as the price of chartered flights is well above what the vast majority of people can afford, regardless of their time values.

Substitution at the Margin

The rational-choice argument is strongest for specific, time-sensitive trips rather than regular travel. Missed connections, limited commercial routes or urgent family situations can make private jet hire a practical cost-benefit decision. On-demand charter platforms have also broadened access, allowing more professionals to consider private jets for individual high-stakes journeys rather than regular use.

The shift towards more cost-effective domestic travel illustrates how an increasing proportion of business travellers have changed their spending habits. While Becker's theory provides an adequate rationale for high-income earners (a group that would benefit from more cost-effective travel options), the evidence from the income elasticity analysis shows that the expense associated with utilising private travel remains more of a marker of luxury than an expense associated with an efficient means of travel for most business travellers.
