Which Airlines Stock Will Offer Better Returns – American Or United?

Given its better prospects, we believe United Airlines stock (NASDAQ
NDAQ
: UAL) is a better pick than its peer, American Airlines stock (NASDAQ: AAL). AAL is trading at a slightly lower valuation of 0.2x revenues than 0.3x for UAL. Investors have assigned a higher multiple to United Airlines stock due to its superior revenue growth and comparatively better financial position, as discussed below.

Interestingly, AAL stock has had a Sharpe Ratio of -0.2 since early 2017, lower than 0.0 for UAL and 0.6 for the S&P 500 Index over the same period.

We compare a slew of factors, such as historical revenue growth, returns, and valuation, in an interactive dashboard analysis of American Airlines vs. United Airlines: Which Stock Is A Better Bet? Parts of the analysis are summarized below.

1. United Airlines’ Revenue Growth Is Slightly Better

• United Airlines’ revenue growth has been slightly better, with a 26% average annual growth rate in the last three years, compared to 25% for American Airlines.
• The rise in revenues for both airlines over the recent years can be attributed to a rebound in air travel demand, with passenger traffic and ticket yield rising meaningfully in the recent past.
• For perspective, American Airlines’ available seat miles declined 25% between 2019 and 2021 but surged 21% y-o-y in 2022. Similarly, its passenger revenue per available seat mile fell 18% between 2019 and 2021 but rose 41% y-o-y in 2022.
• In comparison, United Airlines’ ASM decreased 27% between 2019 and 2021 before rising 39% y-o-y in 2022. Its PRASM declined 19% and increased 43% over the same period, respectively.
• Looking at the last twelve months, United Airlines’ 43% sales growth has fared better than 30% for American Airlines.
• Our American Airlines Revenue Comparison and United Airlines Revenue Comparison dashboards provide more insight into the companies’ sales.
• Looking forward, United Airlines will likely see slightly better sales growth than American Airlines. Both companies will likely see their sales rise at a low single-digit average annual growth rate to around $56 billion in three years, based on Trefis Machine Learning analysis.

2. American Airlines Is More Profitable

• American Airlines’ reported operating margin slid from 7% in 2019 to -60% in 2020 before recovering to 3% in 2022. In comparison, United Airlines’ operating margin fell from 9% in 2019 to -49% in 2020 but rose to 2% in 2022.
• Looking at the last twelve-month period, American Airlines’ operating margin of 9% fares better than 5% for United Airlines.

3. United Airlines Is Comparatively A Less Risky Pick

• Looking at financial risk, United Airlines fares better. Its 214% debt as a percentage of equity is lower than 410% for American Airlines, while its 26% cash as a percentage of assets is higher than 18% for the latter, implying that United Airlines has a comparatively better debt position and more cash cushion.
• The high debt-to-equity figures for both airlines can be attributed to much higher debt levels compared to their market capitalizations ($8 billion for AAL and $14 billion for UAL).
• American Airlines’ total debt increased from $24.3 billion in 2019 to $38.1 billion in 2022, while its total cash increased from around $4.0 billion to $13.4 billion over the same period. However, the rise in cash balance is primarily due to additional debt raised, as heavy negative operating cash flows in 2020 of $6.5 billion almost completely wiped out positive operating cash flows in 2019, 2021, and 2022.
• In comparison, United Airlines’ total debt increased from $15 billion in 2019 to $31 billion in 2022, while its total cash increased from around $2 billion to $9 billion over the same period. However, the rise in cash balance is partly due to additional debt raised, given the $4 billion negative operating cash flows in 2020.

3. The Net of It All

• We see that United Airlines has seen superior revenue growth and has a better financial position. On the other hand, American Airlines is more profitable.
• However, looking at prospects, using P/S as a base, due to high fluctuations in P/E and P/EBIT, we believe United Airlines will likely offer better returns over the next three years, primarily due to its slightly better-expected revenue growth.
• If we compare the current valuation multiples to the historical averages, both appear to have equal upside. American Airlines stock trades at 0.2x sales compared to its last five-year average of 0.4x, and United Airlines stock trades at 0.3x revenues vs. the last five-year average of 0.6x.
• Our American Airlines Valuation Ratios Comparison and United Airlines Valuation Ratios Comparison have more details.

• Although we believe UAL is a better pick over AAL, we acknowledge that 10% returns for UAL isn’t great. There are better opportunities over UAL stock. Our Better Bets Than UAL Stock dashboard details S&P500 stocks that can offer better returns in the next three years.
