Airbus Helicopters H135 vs Airbus Helicopters H145 vs Airbus Helicopters H155 vs Airbus Helicopters H160 vs Bell 525 Relentless vs Leonardo Aw139

The Airbus H135 is a light twin in the small/short-range category, typically configured for about 5–7 passengers, with a range suited to regional hops rather than long point-to-point missions. The Airbus H145 remains a light twin but steps into a higher-utility role, commonly carrying roughly 7–9 passengers with a modestly longer practical range and better cabin flexibility for EMS and corporate use. The Airbus H155 is a medium-class twin aimed at offshore and VIP missions, generally accommodating about 8–12 passengers and offering longer legs than the H145. The Airbus H160 is a newer medium twin positioned for premium offshore/corporate work, usually around 10–12 passengers, with improved efficiency translating to competitive medium-range capability. Bell’s 525 Relentless is a super-medium twin designed for longer-range offshore missions, typically around 12–16 passengers with range advantages over traditional mediums. Leonardo’s AW139 sits in the medium twin class with strong multi-mission utility, commonly 12–15 passengers and a range that is competitive for regional offshore and intercity operations, often comparable to or slightly behind super-medium offerings depending on configuration.
