As 2023 winds down, many best-of lists are published this time of year, but what about a busiest list? Travel data platform OAG, which looks at international and domestic airline route performance and trends, has revealed the busiest flight routes in 2023, with Asian destinations dominating this year’s global list.

From January to December 2023, the busiest flight route worldwide was Kuala Lumpur International Airport to Singapore Changi International Airport. The popular route jumped from the number three spot last year to number one with 4.9 million passengers. That’s a lot of people passing through! Overall, Asia-Pacific routes claimed seven of the top 10 busiest international routes, including the third-busiest route (Hong Kong International Airport in China to Taiwan Taoyuan International Airport in Taipei). Rounding out the top five are two South Korean routes out of Incheon International Airport in Seoul that both travel to Japan (Kansai International Airport in Osaka and Narita International Airport in Tokyo respectively).

“Asia continues to have the busiest routes in the world due to its popularity as a tourism hotspot,” said John Grant, chief analyst at OAG, in a news release.

For US domestic flights, the busiest route in 2023 was between Daniel K. Inouye International Airport in Honolulu to Kahului Airport in Maui, both busy airports located in Hawaii. Other popular domestic routes include numerous longer flights between major hubs, like the fourth-busiest route (John F. Kennedy International Airport in New York City to Los Angeles International Airport in Los Angeles) and the No. 10 pick (Los Angeles International Airport to Chicago O’Hare International Airport). Unsurprisingly, the perennial world’s busiest airportAtlanta’s Hartsfield Jackson Airport-appears three times among the top 10 busiest routes.

Mad Mex’s New Menu Item Is Inspired by a Popular Mexican Street Food

mad mex chicken al pastor

Mexican restaurant chain Mad Mex has dropped a new protein, and it’s one of the most popular street foods in Mexico.

Enter, Chicken Al Pastor. It’s traditionally made with pork and grilled on a spinning rotisserie with a pineapple sitting a top, but Mad Mex has put its own spin on it, serving chicken bathed in an Al Pastor marinade with a touch of juicy pineapple.

You can order the protein-packed filling in your favourite burrito, bowl, quesadilla, nachos, or in a taco.

As always, these things are here for a good time, not a long time. Pop into your local Mad Mex restaurant, order delivery or through the Mad Mex app today.
