There is also evidence that long-haul journeys are • seen by passengers as different, more desirable, to the more commoditised short-haul markets, and so income elasticities are higher the longer the distance. This suggests that middle to lower income individuals are more likely to travel on short to medium haul routes, with higher incomes leading to a higher frequency of long haul travel.
The income elasticity results are based on information from the review of previous studies and results from the new econometric research. Table 2 outlines the estimated income elasticities for different markets at the route and at the national level.
