The following case study has been extracted from IATA (2008) report on "Air Travel Demand". According to Giovanni Bisignani (2008), Director General & CEO, IATA, "The impact on demand of every air transport policy decision is an essential consideration. Without it, uncertainty over demand leads to ineffective or counter- productive decisions." Air Travel Demand Elasticities The elasticity of air travel demand varies according to the coverage and location of the market in which prices are changed and the importance of the air travel price within the overall cost of travel. The appropriate elasticity to use will depend on the type of question being asked. What is the price that is being changed (e.g. an individual airline ticket price or prices within the market as a whole)? What is the unit of demand that is being assessed (e.g. demand for an individual airline or demand for total air travel)? Examining the traffic impact of a price increase on a given route requires a different elasticity than when examining the impact of an across-the-board price increase on all routes in a country or region. There often appears to be some confusion in policy discussions about the sensitivity of airline passengers to the price of travel. This has increased as the industry has changed, with the Internet increasing price transparency, deregulated markets and no frill carriers increasing competition and corporate travel buyers becoming more price sensitive. In particular, there is an apparent paradox whereby: • Passengers are becoming increasingly sensitive to price, led by the boom in low cost travel, the transparency brought by the Internet and the intense competition on deregulated markets. • But, passengers are also becoming less sensitive to price, as increasingly lower air travel prices, in real terms mean that the air travel price itself becomes a smaller and less important part of the total cost of a typical journey. There appears to be an inconsistency between the size of price elasticities estimated for the air transport industry and those estimated for the overall travel and tourism industry. But there are two main explanations for this. Firstly, as the air travel component of the journey can be relatively easily substituted between airlines, routes, modes, etc, the price elasticity for the air travel price can be much higher than suggested by the price elasticity of the overall journey cost. Secondly, passengers (especially for short leisure journeys) can use a "two-stage" decision-making process, selecting a flight destination based on the level of air travel price offered and then considering the other costs associated with the journey. The appropriate value of a demand elasticity will vary in accordance to the context in which they are considered. For air transport there are five main levels (for the scope of the market) for which demand elasticities can be estimated: 1. Price Class Level. This the most disaggregate level, where passengers make a choice between different price classes (e.g. first class, business class, economy class) on individual airlines. 2. Airline / Air Carrier Level. This reflects the overall demand curve facing each airline on a particular route. 3. Route / Market Level. At the route or market level (e.g. London Heathrow-Paris CDG or London-Paris), travellers faced with a price increase on all carriers serving a route (e.g. due to an increase in airport fees and charges), and have fewer options for substitution. 4. National Level. At the national level, travel prices are increased on all routes to and from a particular country (e.g. due to a higher national departure tax), giving travellers fewer options for avoiding the price increase. 5. Supra-National Level. This represents a change in travel prices that occurs at a regional level across several countries (e.g. an aviation tax imposed on all member states of the European Union). In this case, the options for avoiding the price increase are even further reduced. In each of the five levels of aggregation, different cross-price elasticities exist, reflecting the availability of substitute options. The own price elasticity at one level of aggregation can reflect both the own price and cross price elasticities at other levels of aggregation. The interaction between these effects adds significant complexity to the analysis, requiring clarity on which own price and cross price elasticities were measured and controlled for. For example, an analysis of route-level elasticities which does not control for route substitution effects may be more appropriate for a national- level elasticity. Page 3 of 6 The evidence and discussion provided in the IATA (2008) report focuses on the appropriate elasticities for the route, national and supra-national level of aggregation Table 1 provides a guideline for the estimated price demand elasticity by level of aggregation and by region. It multiplies the estimate for the relevant level of aggregation by the relevant short-haul and geographic elasticity multipliers.

Previous studies confirmed that air transport income elasticities were consistently positive and greater than one. This suggests that as households and individuals get more prosperous, they are likely to devote an increasing share of their incomes to discretionary spending such as air travel.
