Airbus Helicopters H135 vs Airbus Helicopters H145 vs Airbus Helicopters H175 vs Leonardo Aw139

The Airbus H135 is a light twin-engine helicopter typically used for training, EMS, and short-hop utility work. It sits in the smallest category here, offering the shortest range of the group and a modest cabin best suited to roughly five to six passengers in common corporate configurations (or fewer with medical fit). The Airbus H145 is also a light twin but a size class up, with a noticeably roomier cabin and higher useful load. It generally carries about seven to eight passengers in standard seating and offers a longer practical range than the H135, making it a frequent choice for EMS, law enforcement, and light offshore or utility missions. The Leonardo AW139 moves into the medium twin category, with a larger cabin and higher cruise capability. It commonly seats around 10 to 12 passengers and delivers a longer range than the H145, making it widely used for offshore transport and SAR. The Airbus H175 is a super-medium twin, larger than the AW139 overall, aimed at offshore and SAR with a typically higher passenger count around 12 to 16 and the longest range among these four in many configurations.
