4-panel full color brochure from 1984 for the Eastern Airlines Frequent Traveler Bonus Program which allowed travelers to earn mileage rewards on both Eastern and TWA flights, as well as British Caledonian and SAS international flights.  The brochure explains how to earn frequent flyer rewards, the different reward program tier benefits, and the program's general terms and conditions.

The brochure is in excellent condition.
