Aviation data firm OAG has released the list of the world's longest flights for 2019 in its Busiest Routes 2020 report, highlighting the top 10 longest air routes flown by airlines during the year.

The ever-changing list sees new entrants nearly every year as flight technology evolves and airlines become more ambitious with their route networks. Last year saw the first full year of operations for multiple flights on the list as many launched or re-launched in 2018.

The year saw the Airbus A350-900 XWB best the Boeing 787 Dreamliner in terms of the number of longest routes operated, as well as the continued decline of quad-engine aircraft flying the longest routes. Airbus' new twin-engine jet has been redefining long-haul travel with its capabilities and has earned the top spot for the year.

Seven out of the 10 routes originate or terminate in the US with all but one touching Asia-Pacific as Singapore, New Zealand, and Australia feature heavily on the list. The list is currently set to change with at least two new routes starting in the next year that will shake-up the list including Qantas' planned Brisbane-Chicago route and Air New Zealand's planned Auckland-Newark route.

Here's the full list.
