A uniform, a badge and a set each come with rules about being filmed
The people you would most like to hear from in this metro work for employers that have already answered the question for them.
Flight crew, ramp and cargo staff and the contractors around Hartsfield-Jackson work under employer policies about appearing in commercial content, and appearing in uniform is the clearest line of all. A grateful client in that uniform cannot endorse your firm, however willing they are.
Production work adds nondisclosure on top. Crew hired for a show sign agreements about what they may describe publicly, and a photograph taken in your lobby with a lanyard in shot can breach one. Never name a production, a studio or an employer in anything you publish.
Badge holders at the airport and in federal offices carry their own restrictions, and the working assumption across all of them is the same: permission from the person is not permission from their employer, and the person is often not sure which they are giving you.
Which leaves the material you control. Your own attorneys, your own rooms, and explanations that need nobody else to appear. A narrower field than a marketer would like, and a much shorter path to actually publishing something.
