In general, airlines will not hire cabin crew members who have severe allergies that could pose a risk to their own health or the health of passengers. For example, an airline would not hire someone with a severe peanut allergy to work on a flight where peanuts are served.

In 2026, you can be cabin crew with a nut allergy, but it depends on the severity of the allergy and the specific airline's medical standards. Airlines generally do not have a blanket ban on nut allergies, but during the recruitment process, you must pass a medical assessment to ensure your condition doesn't pose a safety risk to yourself or others while in flight. If your allergy is so severe that it is airborne or triggered by touch (anaphylaxis from trace exposure), many airlines may consider you a liability, as they cannot guarantee a nut-free environment for the crew or passengers. However, if your allergy is manageable with an EpiPen and careful food handling, many carriers will accommodate you. You would be responsible for carrying your own medication and potentially choosing not to eat the provided crew meals. Some airlines are more "allergy-aware" than others, but "reasonable accommodation" is the 2026 standard, provided you can demonstrate that you can perform your safety duties even in an environment where nuts may be present.
