Since the average stage length is related to an airlines network planning and its business model, the empirical results reiterate the role of business models in an airlines ability to attain efficiency. Among all carriers, Spirit Airlines had the highest frequency of reaching the efficiency score of one, which was related to its performance in the operations stage. According to the U.S. Department of Transportation (DOT), the airline industry has four basic categoriesinternational, national, regional, and cargo. ", Bureau of Transportation Statistics. United's liquidity stood at a worrying $7.5 billion with a daily cash burn of $25 million per day in June, or $2.25 billion a quarter. While the Office of Aviation Analysis has reviewed the reports for obvious errors, the data are presented as reported by the carriers to the Bureau of Transportation Statistics and have not been verified or compared to publicly filed financial documents. In this study, we employed the two-stage centralized network DEA model proposed by Liang et al.

The U.S. airline industry has changed dramatically since the mega-mergers that occurred from 2008 to 2013.

For the third quarter of 2021, profits nearly tripled to $2.7 billion. They also found that low-cost carriers are more efficient than full-service network carriers because low-cost carriers were able to adapt more quickly to changes in market demand. /Info 425 0 R

In this study, CASM is used as the input in the first stage. These H outputs from the first stage, called intermediate measures, are used as the inputs in the second stage in producing the final outputs yrj, where r=1,2,,s, of the entire business activity.

Each DMU consumes different amounts of m inputs xij(i=1,2,,m) to produce different levels of s outputs yrj(r=1,2,,s). Since it is not uncommon to see inefficiency in the labor force when the business environment is highly regulated, how to improve labor efficiency, as measured by revenue generated per employee, becomes an immediate task with which carriers should contend. 0000024699 00000 n According to Liang et al.

Alternative ratios for evaluating long-term financial solvency include the total-debt-to-total-equity ratio and the total-debt-to-total-assets ratio. Regional flights stay local to one area, and cargo airlines transport goods, not passengers. Summary of the efficiency scores from the two-stage centralized DEA model, The carriers under full-service network (FSC) category are American Airlines (AA), Delta Air Lines (DL), United Airlines (UA), Alaska Airlines (AS), and Hawaiian Airlines (HA). Sustainable aviation: The need for a European environmental aviation charge.

On the other hand, the empirical results show that the size of full-time employee equivalents exhibited a negative relationship to operating efficiency, indicating that high labor-related costs continue to hinder airlines ability to attain increased efficiency. Based in Warsaw, Poland and Milan, Italy. While a higher LF indicates better capacity utilization, a high LF does not imply better profitability.

It also encompasses Canadian transborder operations and Mexican transborder operations. According to Table Table4,4, the average stage length flown is statistically significant in both the operations and profitability stages.

Review of recent legacy airline mergers in the U.S.: an empirical study from investors perspectives. <<

In a book discussing the efficiency and competitiveness of international airlines, Heshmati and Kim (2016) concluded the following: (1) airlines efficiency was key to achieving profit maximization; (2) while airline size positively impacted output efficiency, larger airlines were less capable than smaller airlines in reaching better cost efficiency; (3) airlines demonstrated adequate productivity efficiency but were less successful in reaching cost efficiency; and (4) airlines needed to incorporate more cost savings initiatives to further strengthen their global competitiveness.

PMC legacy view She is the CEO of Xaris Financial Enterprises and a course facilitator for Cornell University. (2011), to ensure DEA models ability to differentiate efficiencies among the DMUs, the minimum sample size a study needs is at least twice the product of the number of outputs and number of inputs.

Therefore, the impact of fuel prices is universal, rather than a company-specific variable. FOIA World Air Transport Statistics, Plus Edition 2020 (Report #8288-64). The majority of studies on airline efficiency focus on airlines based in the U.S. and Europe.

Transport and Environment, European Federation for Transport and Environment, Brussels 98(1). International flights typically carry more than 130 passengers from one country to another. Our regression results also indicated that the size of airlines, approximated by total assets, promotes higher operating efficiency, indicating the importance of reaching economies of scale (Heshmati & Kim, 2016) and confirming the arguments that recent mergers have yielded a pro-competitive effect (Carlton et al., 2019). According to the International Air Transport Association (IATA), in 2019, the industry contributed $2.7 trillion in GDP and carried more than 4 billion passengers and 60 million cargo tons. <> The inclusion of this variable helps to identify how airlines route planning decisions, many of which are the results of the business model adopted, affect attainable efficiency.

However, traditional DEA models treat the production process as a single black box and cannot address the interactions between different production stages within a corporate entity.

Transportation Research Part d: Transport and Environment. Variables such as the average stage length flown, total assets, fleet size, and full-time employee equivalents were converted into their logarithmic transformations to rescale the data. The authors did not receive any funding for this study. The industrys high operating leverage makes its profits very sensitive to fluctuations in air-traffic demand.

Regarding the size of an air carrier, Merkert and Morrell (2012) supported the economies of scale argument but cautioned that when airlines seating capacity passes 200 billion available seat kilometers, it will be difficult for the company to operate efficiently. DEA is a nonparametric approach for calibrating the relative efficiency of an entity, called the decision-making unit (DMU), within a group of peer entities who utilize common inputs to produce common outputs. Lee BL, Worthington AC. Carriers can move between groupings (Majors and Nationals) based on the criteria listed below over time.

Our two-stage performance evaluation framework is illustrated in Fig.

Simar and Wilson (2007) pointed out that employing conventional truncated regressions to examine how exogenous variables affect the resulting non-parametric DMU scores is inadequate because of the serial correlation presented in the estimated DEA scores. You can learn more about the standards we follow in producing accurate, unbiased content in our. 0000003996 00000 n /Prev 489743 As the ultimate goal for corporate operations is to maximize shareholders wealth and room for further improvement in the operations stage is limited among carriers, our empirical findings disclose that companies may see more visible breakthroughs in the overall efficiency if attention is given to the profitability stage, where resource allocation becomes vital. Regarding airline performance assessment, Yu (2016) stated that there has been a shift in empirical modeling from index procedures and OLS estimations in the earlier years to DEA approaches in recent years. 0000026324 00000 n Certain data in this review are classified in two broad categories: namely Domestic and International services. :x6/#x!r.hgW&NWS1Ngb =rr=IX}ZGE5wu[BloY-7|ZO8f3e |vGSVLZG|F5:W-_w0 /~rA wvGGoH^)Z3O:;=89h;lnKj Wyw fWIO7vx/5f9 Cev},f'~_OWQ](=QZ4 She earned a Ph.D. in Financial Economics from The Graduate Center, The City University of New York.

The traditional carriers had similar revenues, with an average of $1.5 billion. Passenger revenue declined by 87%, thanks to a relatively strong domestic revenue of $1 billion. >> While students of the airline industry are typically well versed in operational issues, cost and revenue measures, there is less knowledge of the financial position and condition of individual companies. In contrast, American Airlines, United Airlines, and JetBlue Airways were the three carriers with no occurrence of full efficiency in either the first or second stage. The full-service network carriers analyzed were American Airlines (AA), Delta Air Lines (DL), United Airlines (UA), Alaska Airlines (AS), and Hawaiian Airlines (HA); and the low-cost carriers were JetBlue Airways (B6), Southwest Airlines (WN), Spirit Airlines (NK), and Allegiant Air (G4).

Even if half require a refund, and the cash burn remains unchanged, Delta will run out of liquidity in less than a year from now. All other operations are considered International services, which includeoperations in the Atlantic, Latin, and Pacific regions. This gives Southwest a significant advantage when it comes to obtaining more debt at a lower cost or increasing capital expenditure once the pandemic ends. 0000004168 00000 n (2008), constant returns to scale are assumed, and the overall centralized efficiency score is defined as the product of the efficiency score from stage one and the efficiency score from stage two.
