The Alda Jane Lewis Flight Attendant Collection is comprised of visual and textual materials collected by Lewis from 1946 to 1950 during her time as a United Airlines (UAL) flight attendant.

The material covers Lewis's training and active service as a Mainliner stewardess and includes personnel records, such as incident reports, compliment letters, and stewardess air logs, and six photographs which depict Lewis in her stewardess uniform. There is a large amount of United Airlines documentation, including training and on-the-job reference materials, such as how to handle passenger discomfort, employee memos and newsletters, flight menus, route maps, and UAL brochures about the Mainliner. Additional documentation includes material related to the Air Line Stewardesses Association (labor union), including a 1949 labor agreement booklet and the constitution and by-laws of the association and various ephemera, such as a Washington Pilots Association decal, two typed sheets of assorted recipes, and two books.

While most of the collection relates to Lewis's career with United Airlines, there are a few materials from two other airlines: Pan American World Airways and Northwest Airlines. Included are postcards featuring various locations serviced by the airlines, in-flight menus, decals, and route schedules. At the end of the collection are some personal materials.
