Being 150cm (approx. 4'11") makes it challenging but not impossible to become a flight attendant, as most airlines have a minimum height requirement starting between 155cm and 160cm. The reason for these limits is purely functional: crew members must be able to reach emergency equipment (like oxygen bottles and fire extinguishers) stored in overhead bins and be able to close the heavy overhead locker doors. For example, Emirates and Qatar Airways require an "arm reach" of 212cm while standing on tiptoes. However, some regional airlines or those with smaller aircraft (like the Embraer or CRJ series) may have lower height requirements because the cabin ceilings are lower. If you are 150cm, your best strategy is to look for airlines that use a "functional reach test" rather than a strict height measurement. If you can demonstrate that you can safely access all required safety equipment, some carriers may grant an exception. Always check the specific "physical requirements" section of an airline's career page before applying to ensure you meet their safety-critical standards.
