Membership Cards
Members of a loyalty program hold membership cards that represent the membership of that particular loyalty program. A membership card reflects the program and tier to which the card holder belongs; for example, the named holder of a World Flyer Plus Gold card is in the Gold tier of a World Flyer Plus program.
