Demand for international airlines has been very volatile over the past five years. Much of the industry benefited from a constant need for travel, both for seasonal vacations and business trips. The ongoing economic recovery from the pandemic and pent-up consumer demand led to revenue spikes. But lately, much of the industry has been dealing with high costs and debt, lowering profit levels. Overall, revenue has expanded at a CAGR of 15.8% to $96.8 billion over the past five years, including a gain of 1.2% in 2025 alone. Industry profit has climbed to 3.0% of revenue in 2025, up from -21.3% in 2020. International tourism from US and non-US residents has rebounded lately, boosting this industry. Charging ancillary fees such as checked baggage fees and seat selection fees have helped airlines generate more revenue in the period, even though the government views these practices with concern. A potential shortage of pilots is a cause for concern for this industry as more pilots are about to reach retirement age. Airlines are countering this problem by hiring more new pilots. Revenue is expected to stagnate in the coming years as geopolitical conflicts restrict where airlines can operate, harming revenue streams. At the same time, regulations regarding charging junk fees are anticipated to continue being scrutinized by the government, which will keep their operations in check. However, climbing international travel activity will help airlines limit revenue declines during the outlook period. A need for labor will maintain high wage costs, and the reality of labor unions representing pilots and mechanics also poses an issue to airlines due to higher wage expenses. Overall, industry revenue is expected to decline at a CAGR of 0.1% to $96.5 billion over the five years to 2030.

Mainline fleets are expanding aircraft size to carry more passengers per flight, enhancing economies of scale. Major carriers, like Delta Airlines, focused on advancing premium service offerings, while the competitive landscape was further shaped by budget airlines offering low-cost fares. Revenue is expected to expand at a CAGR of 20.6% to $204.5 billion through the end of 2025, including growth of 0.6% in 2025 alone. The double-digit CAGR is attributed to the low comparison base recorded in 2020. Rebounding travel is providing airlines with an opportunity to attract more travelers by offering appealing fare options and continuing to enhance service quality. Easing inflationary pressures and interest rate reductions are improving consumer and business sentiment and driving a rebound in passenger and business travel, supporting growth through 2025. Airlines are capitalizing on this positive momentum, with investments directed toward enhancing customer loyalty programs and expanding their service offerings. Despite facing competitive pressures from low-cost carriers, major airlines are strategically positioning themselves through partnerships and aligning with financial institutions to secure funding.

Global airlines have dealt with an unprecedentedly volatile market over the past five years. In contrast with earlier periods, the industry had to contend with nearly all travel halting during the pandemic. Airlines have largely recovered from the effects of these shutdowns, though revenue is still struggling to return to pre-pandemic levels. Revenue has dropped at a CAGR of 0.1% to $882.2 billion over the five years to 2024, despite an expected expansion of 12.3% in 2024 alone, stemming from an anticipated rise in global tourist arrivals. Airlines have relied on ancillary fees to prevent revenue from collapsing. However, such decisions come at the whim of certain nations like the United States, raising concerns about the practice and causing slight alarm for US-based companies. With fuel being a major input, the recent price volatility of such items has been shaking up their costs, keeping profit on a bumpy ride, though it's now largely back on track. Airlines have also dealt with an evolving need for labor, elevating their wage costs. However, issues with certain suppliers unable to boost their delivery numbers in 2024 are slowing their hiring, helping boost this industry's profit. As such, industry profit will account for 6.9% of revenue in 2024. Global airlines will return to growth, fueled by stronger downstream needs for travel, which will help scale up this industry. However, labor costs will pose an issue for profit growth, as they will elevate wages for workers. Evolving regulatory barriers may also cut down on how much this industry can operate, as it will have to respond to governmental decisions.
