Height requirements for cabin crew vary significantly between airlines but are primarily based on the functional need to reach emergency equipment and overhead bins. Most major international carriers, such as Etihad Airways, require a minimum height of 163 cm (approx. 5'4"), while others like IndiGo set a minimum of 155 cm (approx. 5'1"). Some airlines, like Emirates or Qatar Airways, use an "arm reach" test instead of or in addition to a height measurement, typically requiring candidates to reach 212 cm (approx. 6'11") while standing on their tiptoes. This ensures that the crew can safely operate the heavy doors and retrieve safety gear from the highest storage areas. Weight must also be "proportionate to height" to ensure the crew can move freely through narrow aisles and exits. While the industry has become more inclusive, these physical standards remain a mandatory part of the "fit-to-fly" assessment during the recruitment process to guarantee the safety and security of all passengers in the cabin.
