Tired of flight delays? These are officially the world's most punctual airlines

In an increasingly crowded aviation landscape, the latest on-time performance rankings reveal which airlines prove most dependable.

If there’s one thing every traveller prays for, it’s punctuality. Whether you’re relying on a late-night red eye, planning catch-ups between connections, or simply craving a stress-free start to your holiday, an on-time flight feels like winning the travel lottery.

But which airlines actually stick to their schedules? Using global flight data to track departures and arrivals, Circium’s On-Time Performance Review cuts through the chaos to reveal which carriers are the most reliable coming into 2026.

Which airline came out on top?

When it comes to dependable performance, a handful of global airlines stand out – but one carrier in particular has distinguished itself from the rest. From consistently punctual departures to regular on-time arrivals, Aeromexico is setting the benchmark for reliability.

It marks back-to-back wins for the national carrier, the second airline to claim top spot two years in a row since the review’s 2009 launch. Recording a 90.02 per cent on-time arrival rate across 188,859 flights, Aeromexico proves that in an era of flight delays, reliability is still achievable. Of course, punctuality is only one part of the equation, with many travellers also seeking airlines with the highest safety ratings.

Operating out of three primary hubs – Mexico City, Monterrey and Guadalajara – Aeromexico offers extensive coverage around the country, from holiday hotspots like Cancún and Cabo to regional centres such as Reynosa and Tapachula. Passengers can choose from 48 national routes in total, with many of them running daily.

Beyond its domestic network, Aeromexico services a wide range of international routes, with flights to major European capitals including London, Paris, Madrid, Amsterdam and Rome, as well as destinations across the United States, Canada and Asia. Growth is set to continue in 2026, with new routes planned across the USA and more expected to follow.

How was the winner decided?

In the aviation industry, a flight is considered on time if it pulls up to the gate in under 15 minutes of its scheduled arrival time. An on-time departure is measured under the same time constraints. Using these figures, Circium can track the punctuality of more than 600 airlines across the globe.

But how is this data gathered? The team of aeronautic analysis experts use over 3000 live sources, from the airlines themselves to the airports they fly into. They also have access to satellite flight trackers, civil aviation authorities, global distribution systems, air navigation service providers and more.

Over 99 per cent of scheduled flights worldwide are tracked by Circium, which includes more than 25 million daily flight status updates and up to 180,000 live plane positions per day. With the help of sophisticated analytical platforms and cutting-edge technology, this data is processed and evaluated to provide industry insights and improvements across the board.
