Is Delta the Best Airline Stock to Buy After Its Strong Q3 Results?

Delta Airlines (DAL) reported robust Q3 results, with sales of $16.67 billion and EPS of $1.71 significantly exceeding estimates, driven by strong premium and corporate travel demand, loyalty program growth, and improved operating margins to 11.2%. The company also issued an optimistic Q4 outlook, projecting revenue growth of 2-4% and EPS of $1.60-$1.90, both above consensus, and reaffirmed full-year free cash flow targets. This performance solidifies Delta's position as the largest and most profitable U.S. domestic airline by revenue, leading to an 8% stock surge and suggesting potential for future analyst upgrades despite its current 'Hold' rating.

Analysis

Delta Airlines (DAL) reported robust Q3 results, with sales of $16.67 billion, a 6% year-over-year increase, comfortably surpassing estimates. EPS spiked 14% to $1.71, significantly exceeding consensus. Growth was driven by a 9% rise in premium revenue, an 8% increase in corporate sales, and a 9% uptick in SkyMiles revenue, supported by a 12% increase in American Express partnership earnings to $2 billion.

Operating margins improved notably to 11.2% from 9.4%, indicating enhanced efficiency. Delta's Q4 guidance projects a 2%-4% revenue increase and EPS between $1.60-$1.90, both exceeding current Zacks consensus estimates, driven by strong holiday travel demand. Full-year free cash flow targets of $3.5-$4 billion and a margin outlook of 10.5%-12% were reaffirmed.

Delta has solidified its position as the largest domestic airline by revenue and the most profitable, outperforming United (UAL) and American Airlines (AAL). Despite a year-to-date stock decline of 1%, DAL's 9X forward earnings valuation is on par with the industry average and UAL, making it relatively attractive compared to AAL's stretched 33X P/E. The stock surged 8% post-earnings.

This strong performance and optimistic guidance suggest potential for future analyst upgrades, with earnings estimate revisions likely to trend higher despite the current Zacks Rank #3 (Hold). Delta's diverse revenue streams and profitability position it favorably, indicating that "smart money" may increasingly favor DAL among major airline stocks.

Key Decisions for Investors

• Investors should closely monitor Delta's continued operational efficiency and the trajectory of its premium and corporate travel segments, which are key growth drivers.
• Consider the potential for positive analyst revisions and a re-rating of DAL stock, given its strong guidance and competitive positioning as the most profitable domestic airline.
• Evaluate DAL's valuation relative to peers, noting its comparable forward P/E to United but significantly more attractive multiple than American Airlines, despite its current Zacks #3 (Hold) rank.
