i agree with above. it sounds like you have exactly the kind of experience that an airline needs.
remember.. most airlines are looking for someone professional, level headed, hard worker but immaculately groomed and presented - so yes to makeup, hair in neat ponytail/bun/french roll, nice hands/nails, lipstick, minimal jewellery and neatly pressed interview clothes.
Emphasise your safety role in your resume.. highlight your communication skills, customer service, ability to deal with difficult situations, difficult people, time constraints, workplace legistlation and requirements etc all while maintaining a professional image.
As DJTibby said.. Safety before customer service, but customer service always with a smile
good luck!
