Monday, May 19, 2008 - A group of 20 selected passenger airlines reported a system operating loss margin of 0.02 percent in the fourth quarter of 2007, the first loss after six consecutive profitable quarters, the Bureau of Transportation Statistics (BTS) of the U.S. Department of Transportation reported today in a release of preliminary data. The 20-carrier group consists of the largest network, low-cost and regional carriers based on operating revenue.

BTS, a part of the Research and Innovative Technology Administration, reported that the profit margin in the October-to-December period was the first loss since the first quarter of 2006. The industrys larger airlines, the network carriers, reported an operating loss margin of 1.1 percent. Operating margin measures profit or loss as a percentage of the airlines total operating revenue.

The 20 carriers spent 29.0 percent of their operating expenses in the fourth quarter of 2007 on fuel, compared to 13.5 percent five years earlier in the fourth quarter of 2002 (Table 5). With this quarters release, BTS has added tables on airline fuel expenses. See Tables 5-9.

This release consists of domestic plus international, or system, financial reports for the airlines.

The network groups operating loss margin of 1.1 percent in the fourth quarter was a 2.8 percentage point decline from the 1.7 percent profit margin in the fourth quarter of 2006 (Table 1). The seven network carriers reported a combined operating loss of $274 million in the fourth quarter for the groups first loss after six consecutive quarterly profits. In the fourth quarter of 2006, the seven network carriers operating profit was $392 million.

The regional carriers reported a 3.6 percent operating profit, down from a 7.5 percent profit margin in the fourth quarter of 2006. The seven regional carriers reported a $93 million operating profit in the fourth quarter of 2007 (Table 1).

The top three operating profit margins were all reported by regional carriers Atlantic Southeast Airlines, SkyWest Airlines and American Eagle Airlines (Table 4). Regional carrier ExpressJet Airlines and low-cost carriers Spirit Airlines and Frontier Airlines reported the worst operating loss margins (Tables 2-4). ExpressJet operates both point-to-point service under its own brand and regional service under contract for network carriers. Alaska Airlines reported the worst margin of the network airlines.

America West Airlines and US Airways are now operating under a single certificate and are reporting jointly for the first time. The combined airlines financial numbers are included with the network carriers while US Airways previous numbers remain with network carriers and America Wests previous numbers are listed separately as a low-cost carrier.

Network carriers operate a significant portion of their flights using at least one hub where connections are made for flights on a spoke system. Low-cost carriers are those that the industry recognizes as operating under a low-cost business model, with lower infrastructure costs and higher rates of productivity. Regional carriers provide service from small cities, using primarily regional jets to support the network carriers hub and spoke systems. The selected groups consist of those airlines in each group with the highest reported operating revenue in the most recent 12-month period.

Allegiant Air replaced ATA Airlines as one of the top six low-cost carriers and Horizon Air replaced Pinnacle Airlines as one of the top seven regional carriers because of updated revenue calculations. Allegiants previous year numbers are included in the low-cost tables and Horizons previous year numbers are in the regional tables.

The regional carriers spent the most for fuel per available seat-mile (ASM) of any carrier group while the low-cost carriers spent the least. However, the low-cost carriers spent the largest portion of their operating expenses for fuel while the network carriers spent the least (Table 5).

Regional airlines Atlantic Southeast, American Eagle and Comair spent the most for fuel per ASM while regional airline ExpressJet and low-cost airlines Southwest Airlines and JetBlue Airways spent the least (Tables 6-8).

Regional airlines Allegiant, Atlantic Southeast and low-cost JetBlue spent the largest portion of their operating costs for fuel while regionals Express Jet and Horizon and network airline US Airways spent the least (Tables 6-8).

The regional carriers reported the highest unit costs in the third quarter at 14.9 cents per ASM, slightly more than the network carriers unit costs of 14.5 cents per ASM. The low-cost carriers reported unit costs of 9.5 cents per ASM (Table 9).

The carriers with the highest unit costs were regional airlines Horizon, Comair and American Eagle (Table 12). The carriers with the lowest unit costs were low-cost carriers JetBlue, Allegiant and Southwest (Table 11). US Airways reported the highest unit costs of any network airline (Table 10).

The low-cost carriers were the only group to report lower unit revenues in the fourth quarter of 2007 compared to the fourth quarter of 2006. The low-cost airlines unit revenues of 9.7 cents per ASM were 0.1 cents per ASM less than the unit revenues in the fourth quarter of 2006. Regional airline unit revenue grew 0.2 cents while network unit revenues rose 0.9 cents per ASM from the fourth quarter of 2006 to the fourth quarter of 2007 (Table 13).

The highest unit revenues were reported by regional carriers Comair, American Eagle and Horizon (Table 16). The lowest unit revenues were reported by low-cost carriers Spirit, Allegiant and JetBlue (Table 15). US Airways reported the highest unit revenues of any network airline (Table 14).

The regional airlines passenger yield was the highest of the three groups at 20.8 cents per RPM and also showed the largest increase over the fourth quarter of 2006 at 0.8 cents per RPM (Table 17). Passenger revenue yield measures passenger revenues against total travel by dividing passenger revenues by RPMs.

The top passenger revenue yields were reported by regional carriers Comair, American Eagle and Horizon (Table 20). The lowest passenger revenue yields were reported by low-cost carriers Allegiant, Spirit and JetBlue (Table 19). Alaska reported the highest passenger yield of any network carrier (Table 18).

Airline financial data from the fourth quarter of 2007 and previous quarters are posted on the BTS website at TranStats, the Intermodal Transportation Database, http://www.transtats.bts.gov/Fields.asp?Table_ID=295. Data are compiled from quarterly financial and monthly traffic reports filed with BTS by commercial air carriers.

Financial and traffic data are preliminary and include data received by BTS as of April 24. Data are subject to revision. BTS will release first quarter 2008 financial data on June 16.
