In 2025, global airline stocks are surging, driven by renewed travel demand, strategic route expansion, and sustained financial recovery from the pandemic’s economic impact. Investors are increasingly drawn to leading carriers in the United States, Mexico, Canada, and South America. Among the top performers are Delta Air Lines, United Airlines, and Alaska Airlines in the U.S., while Volaris and Copa Airlines gain momentum in Latin America. Meanwhile, Air Canada and LATAM Airlines Group emerge as strong contenders in their respective regions, appealing to long-term investors seeking reliable airline stocks.
Delta, United, and Alaska Take the Lead in U.S. Airline Market
The U.S. airline industry continues to show robust recovery and strategic positioning.
Delta Air Lines (NYSE: DAL) has seen a 77% stock increase over the past year, thanks to its premium service model and consistent profitability. The Atlanta-based airline maintains one of the broadest international networks and focuses on high-margin routes, particularly transatlantic and premium leisure. Delta’s operational efficiency and customer satisfaction rankings make it a key investment target.
United Airlines (NASDAQ: UAL) has outpaced expectations with a 154% year-over-year stock increase. The Chicago-based carrier is leveraging international expansion into markets like Latin America and Asia. Its winter 2025 route additions to destinations such as Tepic (TPQ), Mexico; and Punta Cana (PUJ), Dominican Republic, show aggressive growth strategy.
Alaska Airlines (NYSE: ALK) is thriving on West Coast demand and eco-tourism routes. With new services to Baja California Sur and Monterrey, Mexico, Alaska’s strategy aligns with sustainable travel trends. Its Relative Strength Rating rose to 74 in early 2025, signaling a stock on the rise.
Latin America’s Rising Stars: Volaris and Copa Holdings
Latin America’s aviation sector is attracting global investor interest, fueled by budget travel demand and strategic expansion.
Copa Holdings (NYSE: CPA), headquartered in Panama City, operates one of the most efficient hub-and-spoke systems in the Americas. With over 60 destinations and operating margins over 20%, Copa remains one of the most profitable airlines in the hemisphere. Recent route additions to the Caribbean and South America reinforce its investment appeal.
Volaris (NYSE: VLRS), Mexico’s leading ultra-low-cost carrier, has expanded its domestic and cross-border routes significantly. While analysts flag liquidity risks (a current ratio of 0.69), the airline’s passenger growth and market share gains make it a compelling long-term bet. Volaris exceeded Q2 earnings estimates, reflecting operational resilience.
Canada’s Air Canada and Cargojet Deliver Promising Returns
North of the U.S. border, Canadian airline stocks are gaining traction.
Air Canada (TSX: AC) is executing one of its largest winter expansions to Latin America and the Caribbean, adding routes from Toronto, Montreal, and Vancouver to Belize, Guatemala, Cartagena, Puerto Vallarta, and more. Despite facing some labor unrest, Air Canada is strengthening its post-pandemic recovery with increased international demand and loyalty program growth.
Cargojet (TSX: CJT), a cargo-only airline, stands out as a unique investment. As e-commerce expands, Cargojet’s role in time-sensitive freight is more critical than ever. It remains a market leader in overnight air cargo services across Canada and partners with major retailers and couriers.
LATAM Airlines: South America’s Aviation Powerhouse
LATAM Airlines Group (NYSE: LTM), headquartered in Santiago, Chile, operates across South America, including Peru and Brazil. LATAM is spearheading aviation recovery in the region with a focus on domestic connectivity and regional market dominance. The airline’s stock is rebounding alongside GDP recovery in core South American markets. LATAM’s plans for fleet modernization and increased North American connectivity are enhancing its investment profile.
