2018 will see Airbus and Boeing launch their latest passenger-packing jets, which extend the framework of current Airbus A350 and Boeing 787 designs to carry even more travellers from tip to tail.
First up is the Airbus A350-1000, which global launch customer Qatar Airways will begin flying this month (and shown below in the company of the smaller A350-900).
Airbus specs the A350-1000 as 366 passengers "in a standard three-class configuration", compared to a comparable 325 passengers on the A350-900.
However, Qatar's A350-1000 will be decked out with just 327 seats across two cabins: there'll be 46 of the elegant Qsuites in business class, and 281 economy seats down the back of the bus, compared to 283 seats on the Oneworld member's A350-900 jets.
Those Qsuites will be divided into 22 forward-facing and 26 rear-facing business class suites...
... with the middle suites able to convert to six double beds...
... and six 'quad suites'.
The elongated Boeing 787-10 is expected to follow in March when Singapore Airlines picks up the keys to the newest member of its fleet.
Boeing pegs the 787-10's capacity at some 330 passengers over two cabin classes, although there's no word yet on Singapore Airlines' own cabin configuration.
What we do know is that this biggest Dreamliner will see the debut of an all-new regional business class seat, embracing a pod-like design with a lie-flat bed and direct aisle access for every passenger.
It's understood that the 787-10, like its regional Airbus A350-900 siblings, won't have a premium economy cabin.
Australia is highly likely to see the Boeing 787-10 appear on some routes, although the airline's flagship Airbus A380 and Boeing 777-300ER will remain in the mix for larger cities such as Sydney and Melbourne.
