A321neo vs A340-600: the key differences

  • The A340-600 delivers 88% more range (A321neo: 4,000 nm; A340-600: 7,500 nm).
  • The A340-600 delivers 0% more cruise speed (A321neo: 487 kt; A340-600: 488 kt).
  • The A340-600 delivers 56% more passenger capacity (A321neo: 244 seats; A340-600: 380 seats).
  • The A321neo is the newer design (introduced 2017 versus 2002 for the A340-600), a gap of 15 years that usually shows up in avionics, cabin systems and fuel burn.
  • The A340-600 is the larger aircraft by maximum takeoff weight (837,756 lbs versus 213,848 lbs), which typically buys more cabin and payload at the cost of higher trip economics.
  • The two differ in powerplant layout: the A321neo runs 2 engines against 4 on the A340-600 — a factor in redundancy, maintenance scope and operating cost.

Which mission suits which aircraft

The A340-600 is the stronger fit for nonstop ultra-long-haul routes — its 7,500 nm of range removes fuel stops on those legs. The A321neo, at 4,000 nm, is better matched to long-haul and transatlantic missions, where lower trip cost counts for more than outright reach. If most of your flying sits inside the A321neo's range, the A340-600's extra capability is range you pay to carry but rarely use.

Which should you choose?

On published specifications the A340-600 leads on both range and cabin capacity, so it suits operators who want maximum mission flexibility from a single airframe. The A321neo 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.
