Yes, you can be a member of the cabin crew if you have asthma, provided that your condition is well-controlled and does not interfere with your ability to perform safety-critical duties. During the recruitment process, all prospective flight attendants must pass a comprehensive medical examination. If you disclose asthma, the airline's medical examiner will typically require a report from your doctor or a lung function test to ensure you are fit to fly. The primary concern for airlines is the "hypoxic" environment of a pressurized cabin, where oxygen levels are lower than at sea level, which can occasionally trigger respiratory distress in sensitive individuals. As long as you can manage your asthma with standard inhalers and have not had a severe, debilitating attack or hospitalization in the recent past, you are generally eligible for the role. However, you must be able to demonstrate that you can perform physically demanding tasks—such as fighting an onboard fire or assisting in an emergency evacuation—while wearing a protective breathing diaphragm. Most airlines consider well-managed asthma a manageable condition rather than a disqualifying disability, but individual airline health standards can vary slightly.
