November gave us an early look at how airlines are handling the winter schedule, and the signals were hard to miss. Passenger demand continued rising, with international travel once again pulling ahead of domestic markets.
Zooming out, the picture becomes even more interesting. Asia-Pacific and the Middle East showed strong growth, while other regions moved at a different pace. At the same time, November offered a clear reminder that reliability still matters, as on-time performance faced pressure from rising cancellations and operational disruptions.
So what does all of this mean as winter unfolds? Let’s take a closer look at the key trends shaping performance right now.
Demand Strengthens as Winter Takes Hold
The aviation industry is already deep into the winter schedule, and the latest data from IATA helps explain why networks have been under sustained pressure in recent weeks.
Global air passenger demand grew 6.6% year-on-year, measured in revenue passenger kilometers (RPKs), while total capacity increased by 5.8%.
This imbalance between demand and capacity highlights a familiar challenge. Aircraft are flying fuller, and operational margins are tightening.
International travel remained the key driver. Demand rose 8.5% year-on-year, with capacity up 7.1%. Domestic traffic grew at a more modest 3.4%, broadly in line with a 3.6% increase in capacity.
These trends point toward a busy year-end, with pressure varying significantly across regions.
Asia-Pacific and Middle East Gain Pace
Let’s take a closer look at some of the key regional highlights.
Asia-Pacific continued to lead the global recovery. International demand rose 10.9% year-on-year, supported by a 9.1% increase in capacity. Strong traffic flows to and from China, Japan, and Vietnam drove much of this growth, reflecting the ongoing restoration of regional networks and long-haul connectivity.
Europe also delivered a solid performance, with demand increasing 7.4% and capacity up 6.0%. European carriers benefited from resilient intra-European traffic and steady long-haul demand, entering winter with some of the fullest aircraft globally.
North America showed signs of renewed traction after several months of flat performance. International demand grew 4.5%, while capacity increased 4.7%. Growth on the trans-Atlantic corridor reached 3.8% year-on-year, pointing to a gradual recovery in corporate travel alongside sustained leisure demand.
Middle Eastern carriers posted one of the strongest performances. Demand rose 10.7%, while capacity expanded 8.1%. This momentum was supported by strong hub connectivity and a rebound from last year’s geopolitical disruptions.
Latin America recorded 7.2% demand growth, but capacity expanded faster at 8.2%. Expansion across leisure-focused routes continued, although supply growth outpaced demand in several markets.
Last but not least, Africa saw demand rise 7.3%, with capacity up 5.3%. Despite the positive trend, ongoing infrastructure and operational challenges continue to weigh on load factors.
The Punctuality Challenge as Winter Progresses
November was a challenging month for airline reliability, with disruption levels rising sharply compared to the previous month.
Flight cancellations surged by 40% month-on-month, reaching 43,987 cancelled flights globally, up from 31,461 in October. A key contributor was the global requirement to ground around 6,000 Airbus A320 family aircraft for a mandatory software update, which significantly strained already tight schedules and triggered widespread knock-on delays.
Regionally speaking, North America was hit hardest, reporting 18,145 cancelled flights, a dramatic 200% increase compared to October. Asia-Pacific cancellations rose 17% to 17,256, while the Middle East and Africa saw a 20% increase to 2,300. Latin America recorded a 10% rise with 2,837 cancellations. Europe stood out as the only region to improve, reducing cancellations by 44% to 3,449 flights.
OTP Rankings: Standout Performers in November
Despite these challenges, several airlines delivered standout performance, as shown in the latest OTP rankings.
Among major airlines operating more than 20,000 flights, Hainan Airlines topped the rankings with an impressive 88.65% on-time performance. They were followed by China Southern Airlines and SAS Scandinavian Airlines, completing the top three.
In the large airline category, defined as carriers operating between 10,000 and 20,000 flights, Aeromexico led the way with an exceptional 91.67% OTP, operating 15,223 flights and cancelling just eight services during the month.
Europe also saw strong individual performances. ITA Airways stood out with only two cancellations and an OTP of 88.49%, while SunExpress reported zero cancellations and an OTP level of 88.13%. Among low-cost carriers, Wizz Air delivered the highest OTP at 86.72%, with just 19 cancellations.
By contrast, FAA-imposed restrictions in the United States contributed to higher disruption levels for several major carriers. American Airlines cancelled nearly 5,500 flights (2.99% of operations), while United Airlines cancelled 4,043 flights (2.81%), underscoring how regulatory and operational constraints can quickly affect reliability during peak periods.
As airlines push through the busiest weeks of the year, OTP performance remains one of the clearest signals of how well networks are coping under pressure.
Heading Into the Final Stretch of 2025
The past few weeks have offered a clear snapshot of the challenges the aviation industry faces as winter unfolds. Capacity continues to fall short of demand, compounded by persistent staffing and resource shortages.
At the same time, there was a spike in cancellations and a wide spread in on-time performance results. While some carriers delivered standout performance, others struggled with limited capacity, regulatory constraints, and unexpected disruptions.
The final weeks of 2025 will reveal how effectively airlines keep operations on track while balancing demand, reliability, and customer experience during one of the busiest travel periods on the calendar. Maintaining visibility, coordination, and control across operations will be critical. We’ll take a full look at how 2025 shaped up, and what it means going forward, in our December wrap-up.
