Wednesday, July 27, 2005 - The Air Travel Price Index (ATPI) fell 4.3 percent in the first quarter of 2005 from the same period in 2004 (Table 1), marking the lowest first-quarter fare index of any January-to-March period since 1999 (Table 2), the U.S. Department of Transportation's Bureau of Transportation Statistics (BTS) reported today.

BTS, a part of the Research and Innovative Technology Administration, reported that the year-to-year decline in the first-quarter level to 103.9 (1995 1st quarter = 100) was the third consecutive quarter in which the ATPI was lower than the same period a year earlier.

The largest year-to-year fare index increase for the first quarter among the 85 largest airline markets, ranked by passengers, was 11.5 percent in Honolulu, HI, followed by San Juan, PR, Oakland, CA, Burbank/Glendale/Pasadena, CA, and Phoenix (Table 4). The biggest year-to-year fare index decrease was 22.7 percent for itineraries originating in Cincinnati. Other top fare decreases were recorded in Charleston, SC, Philadelphia, Richmond, VA, and Charlotte, NC.

The largest 10-year first-quarter fare index increase was 111.3 percent in Lihue (Kauai), HI. Three of the top five fare increases over this period took place at Hawaiian airports. Anchorage, AK, and Burbank/Glendale/Pasadena, CA, were the non-Hawaiian airports with the top fare increases (Table 5). The biggest first-quarter 10-year fare index decrease was 22.1 percent for itineraries originating in Manchester, NH, followed by Raleigh/Durham, NC, Providence, RI, Philadelphia and Hartford, CT.

The ATPI is a quarterly measure of changes in airfares since the first quarter of 1995 for itineraries on U.S. carriers beginning in the United States. The ATPI was released for the first time in March 2004. The numbers are not adjusted for inflation.

The ATPI in the first quarter of 2005 was 11.1 percent below the level of the first quarter of 2001 when the index reached its highest point of any January-to-March period since the period covered by the data beginning in 1995 (Table 1, 2).

The first-quarter 2005 index rose 1.6 percent from the fourth quarter 2004 level (Table 3). Quarter-to-quarter changes may be affected by seasonal factors.

Additional information about the ATPI, including indexes for foreign-origin itineraries and the top 85 air travel markets based on originating passengers, can be found on the BTS website, http://www.bts.gov/xml/atpi/src/index.xml. The second-quarter 2005 ATPI is scheduled for release on Oct. 26, 2005.

The ATPI series are computed using a price index methodology similar to that used by other federal statistical agencies. Although the ATPI is computed using a tested index methodology, the effective application of this methodology to the airlines' data is still under development and it is considered a research series at this time.

Brief Explanation of the ATPI

The ATPI is based on fares paid by travelers and draws its data from the BTS Passenger Origin and Destination Survey. Through this survey, BTS collects information from the airlines on a 10-percent sample of airline tickets. Each ticket sold is assigned an identification number, and if this number ends in 0, the ticket is in the sample.

The index measures the aggregate change in the cost of itineraries originating in the United States, whether the destinations are domestic or international, but only for U.S. carriers (excluding charter air travel). The ATPI is based on the changes in the price of individual itineraries, that is, round trips or one-way trips for which no return trip is purchased, and the relative value of each itinerary, for the set of matched itineraries.

The index uses the first quarter of 1995 as the reference point (expressed as the number 100) against which all subsequent quarterly prices are measured. ATPI values below 100 represent overall "cost of flying" levels less than those in the first quarter of 1995, while values above 100 represent cost of flying levels that exceed those of the first quarter of 1995. ATPI levels can be used to compute percentage changes in overall fare costs between any two quarters in an ATPI series.

Unlike many other price index estimates, the ATPI is not based on a fixed "market basket" of air travel services. Rather, all of the data from the Passenger Origin and Destination (O&D) Survey are fed into the estimation system each quarter, and this collection of itineraries varies from one quarter to the next. New entry, including routes and carriers, will not be included in the ATPI calculations until it has been present in the O&D Survey for two consecutive quarters.

The ATPI differs from the Bureau of Labor Statistics' (BLS) airfare index, a component of the Consumer Price Index. The BLS index is based on fares advertised through SABRE, a leading computerized airline ticket reservation system, while the ATPI uses actual fares paid by travelers. Since a growing number of tickets are purchased through the internet at discounted prices not listed with SABRE, the ATPI does not show the same levels of increases as the BLS index.

For price comparison purposes, itineraries flown in each quarter are "matched up" with identical or very similar itineraries flown in other quarters. A price index formula is then used to compute aggregate index estimates such as those that appear in this release.

The fares reported in the O&D Survey include taxes, so the ATPI values reflect changes in tax rates as well as changes in fares received by the airlines. The ATPI values in this release are not adjusted for seasonality, so some movements in the series are due to seasonal variations in airfares.
