How This Private-Aviation Training Agency Takes Service to New HeightsSkyAngels is out to make the skies a bit friendlier for flyers.

Steffany Kisling never expected to get into the rarified world of private aviation. "I grew up with meager means. Even a commercial flight was a luxury," she points out.

Today Kisling, a former cabin attendant on flights and yachts, is the founder of a business that specializes in extravagance: San Francisco-based SkyAngels, which trains über-cabin attendants to see to every need of the famous or wealthy who fly high on private planes.
