In 2019, two Qantas flights, one from New York City one from London, set off on two landmark test flights, pushing the limits of ultra-long-haul air travel.

With modern passenger jets now capable of flying for more than 18 hours, ultra-long-haul flights are more accessible than ever. Here we take a look at some of the longest flights available to book now, plus a few coming very soon.
