Quizplus · Accepted Answer

John's frequent flying, especially at such a high mileage and in first class, suggests a very high level of loyalty and revenue generation for the airline. This would likely place him in the highest tier of the airline's loyalty program, which is often symbolized by a precious material. "Diamond" is commonly used to denote the highest tier in many loyalty programs, including those of airlines, due to its association with value, rarity, and desirability.
