Global Airline Industry Set To Hit $1 Trillion By 2025 Despite Supply Chain Turbulence

The global airline industry is on track to achieve record revenues of $1 trillion by 2025, according to the International Air Transport Association (IATA). While passenger numbers continue to rise, the sector faces persistent challenges, including aircraft supply chain disruptions and operational delays.

Record Revenue and Profit Growth

IATA projects a net profit of $36.6 billion for the airline sector in 2025, a rise from the $31.5 billion expected in 2024. Passenger traffic remains strong, with a record 5.2 billion passengers travelling in 2024. Although growth in 2025 is forecasted to be more moderate, it will still contribute to a sustained recovery following the COVID-19-induced collapse of 2020, which saw industry losses of $140 billion.

Lower fuel prices are providing some relief for airlines. Brent crude oil prices have declined by 20% over the past year, easing operating costs. The outlook is further supported by expectations of looser fiscal policies worldwide, which could bolster consumer purchasing power and drive global economic growth.

Supply Chain Disruptions Hamper Expansion

Despite positive financial projections, airlines face significant operational challenges. Strikes and technical issues at major aircraft manufacturers Boeing and Airbus have delayed deliveries of new, more fuel-efficient planes. These delays are problematic for airlines seeking to modernise their fleets and reduce fuel costs.

Boeing’s production of the 737 MAX aircraft was disrupted after a seven-week strike involving more than 70,000 employees. Following a new labour agreement that includes a 38% wage increase over four years, production has resumed. However, the backlog of more than 4,000 pending orders poses a logistical hurdle for Boeing as it seeks to meet growing airline demand.

A Look Ahead

As the airline industry edges closer to the $1 trillion revenue milestone, it must navigate both opportunities and obstacles. Rising passenger numbers and easing fuel costs are key growth drivers. However, production delays at Boeing and Airbus highlight the fragile nature of the sector’s supply chain.

The coming years will be defined by how well the industry adapts to these challenges. Airlines reliant on timely fleet upgrades may face operational setbacks, but the overall outlook remains positive. With strong global demand, increased profits, and declining fuel costs, the sector is poised for continued growth—though not without turbulence along the way.

Irregular Meal Timing May Raise Heart Risk In Men, New Study Suggests

by THEFUTURE.TEAM

September 8, 2026

Eating breakfast at lunchtime or dinner during normal sleeping hours may seem like a minor weekend indulgence. New research suggests, however, that this type of irregular meal timing, described by scientists as “eating jet lag,” may be linked to higher cardiovascular risk in men.

A French study published in Communications Medicine found that each additional hour of eating jet lag was associated with a 14% higher risk of cardiovascular disease and a 21% higher risk of coronary heart disease among men. No similar association was observed in women.

Why Meal Timing Matters

Weekend schedules often differ from weekday routines, with work and school timetables shifting when people eat. Over time, researchers suggest, these changes may interfere with the body’s biological rhythms.

“This study suggests the importance of regular meal-timing patterns, beyond sleep and diet quality, in cardiovascular disease prevention,” the authors wrote.

Researchers followed more than 100,000 participants for 14 years, analyzing the timing of their first and last meals on working days and weekends between 2009 and 2023.

Risk Pattern Appeared In Men

Participants were grouped according to how their meal times changed between weekdays and weekends. One group ate earlier on weekends, another maintained similar schedules, and a third ate later.

Both groups with irregular meal timing showed higher cardiovascular risk than those with stable schedules, regardless of overall diet quality. The association was observed only among men.

Researchers proposed several possible explanations. Men generally have a higher absolute risk of cardiovascular disease, while women tend to have stronger morning-oriented routines that may influence how their bodies respond to changes in meal timing.

Circadian Rhythms May Explain The Link

One possible explanation is that irregular eating disrupts the body’s circadian system, which regulates many physiological functions over a 24-hour cycle.

Light is the main signal that sets circadian rhythms, but food timing also helps synchronize peripheral clocks in organs including the liver and heart. Eating in alignment with these rhythms is generally associated with better metabolic regulation, while irregular timing may disrupt that balance.

What It Means For Prevention

The findings do not prove that irregular meal timing causes heart disease. However, they add to growing evidence that when people eat may matter nearly as much as what they eat for long-term cardiovascular health.

If confirmed in larger studies, regular meal timing could become a useful target for public health interventions aimed at reducing chronic disease risk. For individuals, employers and schools, greater consistency in daily routines may be more than a lifestyle preference and could form part of a broader strategy to protect heart health.
