Chennai International Airport (MAA) delivered the best operational performance among India’s 10 major airports in May 2026, according to the latest data released by the Directorate General of Civil Aviation (DGCA). With an impressive 92.2% on-time performance (OTP), Chennai outperformed several larger aviation hubs, including Delhi, Mumbai, Bengaluru, and Hyderabad, highlighting its efficiency in handling domestic flight operations.

Chennai Leads India’s Airport Punctuality Rankings

On-time performance measures the percentage of flights that depart or arrive according to their scheduled timings. A higher OTP reflects smoother airport operations, efficient ground handling, and fewer delays for passengers.

The top 10 airports ranked by on-time performance in May 2026 were: 

Reasons Behind Chennai Airport’s High OTP 

Chennai’s 92.2% OTP is particularly noteworthy because it surpassed several of India’s busiest airports, including Delhi, Mumbai, and Bengaluru, which handle significantly higher passenger volumes and aircraft movements. The airport’s strong performance reflects:

• Efficient runway and air traffic management.
• Faster aircraft turnaround times.
• Better coordination between airlines, ground staff, and air traffic control.
• Reduced operational delays despite increasing domestic passenger traffic.

For travelers, a higher OTP generally means fewer delays, more reliable departures, and smoother travel experiences.

Domestic Aviation Continues to Grow

The achievement comes as India’s domestic aviation sector continues its steady growth. Between January and May 2026, domestic airlines carried 729.40 lakh passengers, a 1.91% increase over the same period in 2025. In May alone, passenger traffic reached 153.90 lakh, reflecting a 9.49% month-on-month increase.

IndiGo Also Leads Airline Punctuality

The airport’s success was complemented by strong airline performance. Among scheduled domestic carriers, IndiGo recorded the highest airline on-time performance at 82.8%, followed by Akasa Air (78.3%) and the Air India Group (74.5%). Since IndiGo operates a large number of flights from Chennai, its operational efficiency likely contributed to the airport’s impressive OTP.

On-time performance of North American airlines experienced a significant decline during the month of June. Notably Alaska Airlines was the sole carrier reporting an on-time performance of 80.3 percent. According to Cirium’s monthly report, the average on-time performance plunged more than 10 percentage points from the previous month. June recorded a 66.1 percent compared to 78.7 percent a month earlier.

Even Alaska Airlines’ performance had slipped from the May figure of 84.7 percent. As for the other eight carriers, the percentage-point declines varied from 7.1 percent for United Airlines to a staggering 17.7 percent for Air Canada.

Delta Airlines: Global On-Time Performance List

Amidst the global contenders, Delta Airlines stood alone, representing North America on the on-time list. Positioned at the eighth spot, its on-time performance reached a modest 79.7 percent. With this the carrier fell from its previous second-place position in May.

Weather Woes Impacting On-Time Performance of North American Airlines 

One of the major factors contributing to the performance decline was the inclement weather that plagued the region throughout June. Particularly in the New York area, harsh weather conditions wreaked havoc, further compounded by a shortage of air traffic controllers. Moreover, reduced visibility due to Canadian wildfire smoke added to the carriers’ woes, making it difficult for them to adhere to their schedules.

The number of flight cancellations also skyrocketed in June, with North American airlines recording a staggering 17,414 canceled flights, almost triple the 6,042 cancellations in May. Due to this many passengers had to endure the inconvenience of disrupted travel plans.

When is a flight considered to be on-time?

To put it simply, a flight is considered on time when an aircraft arrives at the gate in 15 minutes or less of the scheduled arrival time.

2022 has been a roller coaster ride for the American airline industry. While the robust recovery of travel from the pandemic-induced slump gave hope to the aviation sector, this has also been a year that saw major operational disruptions, especially during the summer travel season recorded a high rate of flight delays and cancellations (due to short staffage and other reasons). To register an on-time performance (OTP) of 84.1% this year can be considered no mean feat, and Delta Air Lines, having achieved this, is named the most punctual airline of North America in 2022. 

In the rankings given by the Aviation analytics firm Cirium to North American Airlines on the basis of their on-time performance in 2022, Delta Air Lines bagged the top spot with a high on-time arrival percentage. Around 84% of Delta’s flights from January 1 through December 15 arrived on time, according to Cirium’s data. Alaska Airlines, with an on-time performance percentage of 81, came next in the rankings followed by United Airlines (81% OTP) and American Airlines (79% OTP) in the third and fourth places respectively.

For its annual On-Time Performance Review for 2022 released on Thursday, Cirium did not take into account the 16-day period after December 15 as the ongoing holiday travel season is witnessing a large number of flight cancellations and delays due to a rapidly intensifying winter storm. 

The aviation analytics firm defined on-time flights as the ones that reach the designated gate within 15 minutes of scheduled arrival time. Of the five million flights tracked by Cirium in North America, nearly 72% are found to arrive on time. 

Here are the 10 most punctual airlines of North America in 2022, according to Cirium.
