Which mission suits which aircraft
Both aircraft are built for nonstop ultra-long-haul routes, so outright range rarely separates them — the call leans on cabin (the 787-9 Dreamliner seats more), trip economics and what is actually available on the market. Match the airframe to how you fly most weeks, not to the headline range figure.
Which should you choose?
On published specifications the 787-9 Dreamliner leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The A340-600 can still be the smarter buy on acquisition cost, operating economics, runway performance, or current availability — the factors that rarely show up in a spec sheet. Our acquisition advisory team can model both against your actual mission profile before you commit.
