1-1 Chapter 1 INTRODUCTION 1.1 This circular has been prepared pursuant to ICAO Assembly Resolution A33-19, Appendix G, which requests the Council to instruct the Secretary General to issue periodically a study on regional differences on the level of international air transport operating costs, analysing how differences in operations and input prices may affect their levels and the impact that changes in costs may have on air transport tariffs. This study on Regional Differences in International Airline Operating Economics 2000 and 2001 succeeds one which covered the years 1998 and 1999 and was published in 2003 Circular 293-AT/125 and one which covered the years 1992 to 1997 Circular 280-AT/117 published in 2000. Prior to that, similar studies were published annually under the title Regional Differences in Fares, Rates and Costs for International Air Transport, which covered the years 1976 to 1992. The studies are now published biennially or every other year, although data have continued to be collected and analysed on an annual basis. The present circular focuses on the years 2000 and 2001. 1.2 For 17 international route groups, comprising all international routes, passenger, freight and mail revenue yield data are presented in Chapter 2 for scheduled services, along with passenger revenue yield data for non-scheduled operations. With reference to the same route groups, regional differences in the costs related to the scheduled service passenger yields are presented in Chapter 3. The major causes of regional differences in costs are identified in Chapter 4. In Chapters 2 and 3, the 2001 results are compared with those for 1999. 1.3 The sources of data used in the study are given in Appendix 1, together with information on the sample sizes on which revenue and cost data are based. The method of analysis used in the study is presented in Appendix 2, together with information on the margins of uncertainty, a factor which should be borne in mind when considering the results of studies of this nature. Facsimiles of the questionnaire and information on responses appear in Appendix 3. 1.4 Unless indicated otherwise, all references to cents in this circular mean U.S. cents and all references to dollars mean U.S. dollars.
2-1 Chapter 2 LEVELS OF UNIT REVENUES Passenger traffic 2.1 Estimates of average unit passenger revenues in 2000 and 2001 by route group are presented in Table 2-1. 2.2 Column 1 of Table 2-1 shows the average revenue per passenger-kilometre for scheduled passenger traffic on each route group for 2000 and 2001. These data are considered representative of all airlines operating on the particular route group and also include estimates for non-reporting airlines. The data are presented without distinction to class of travel or fare type. Thus, they represent the overall weighted average for all individual routes on all route groups and for all fare types. The overall average revenue per passenger-kilometre excluding incidental revenues was estimated at 7.45 cents for 2000 and 7.24 cents for 2001. However, the route group averages vary from a high of 14.6 cents in local Europe to a low of 4.8 cents on routes across the Mid-Atlantic in 2000 and from a high of 14.0 cents in local Middle East to a low of 4.9 cents on routes across the Mid-Atlantic in 2001. Due to inadequate representation in reporting, two route groups local Central America/Caribbean and local Africa are not included in this analysis, although their estimates are included in the worldwide totals for both years. 2.3 Column 2 of Table 2-1 depicts the average revenue per passenger-kilometre for non-scheduled passenger traffic reported for each route group for 2000 and 2001. In this case, no attempt has been made to estimate the unit revenues for non-reporting air carriers. In addition, it should be borne in mind that the average unit revenues may not be for the same set of airlines for both years in each route group. The reason is that the availability of data is limited and dependent upon the reporting of air carriers whose composition may differ from year to year. The average revenue per passenger-kilometre for non-scheduled services ranges from a high of 18.9 cents for traffic between North America/Central America/Caribbean and South America to a low of 4.8 cents on routes within Europe in 2000 and from a high of 13.8 cents on routes within the Middle East to a low of 3.8 cents on routes across the Mid-Atlantic in 2001. Except for routes within Europe, where the bulk of non-scheduled operations is to be found, the non-scheduled traffic reported is limited in volume. It is estimated that non-scheduled traffic represented some 13 and 14 per cent of the total international passenger-kilometres performed in 2000 and 2001, respectively. Columns 3 and 4 of Table 2-1 show the average passenger load factor for scheduled services and non-scheduled services, respectively. 2.4 On a worldwide basis, the estimated average revenue per passenger-kilometre for scheduled services at 7.24 cents in 2001 showed a decrease of some 4 per cent from the level in 1999. Comparable data by route group between 1999 and 2001 are available for only 14 individual route groups. Out of these 14 route groups, 11 showed decreases, ranging from a reduction of some 11 per cent for routes between Europe and the Middle East to some 1 per cent for routes across the North and Mid-Pacific. The increases on the remaining 3 route groups range between 2 per cent for routes between North America/Central America/Caribbean and South America to 4 per cent for routes within North America Figure 2-1. 2.5 The changes in yields experienced between 1999 and 2001 reflect the strengthening of the U.S. dollar against most of the other world currencies, especially the currencies of countries in Africa, Europe, Asia/Pacific and South America. The relative change between 1999 and 2001 would, in many cases, be significantly different if expressed in the national currencies of the airlines concerned. A brief evaluation of this effect is given in Chapter 3 paragraphs 3.11 and 3.12.
