Switching intentions, that is, the opposite of loyalty intentions,were lower among reward program members than non-members in Tanford et al.’s (2011) hotel loyalty research, but base and higher tiers did not differ significantly. In a study of department store customers, reward program membership served as a moderating variable that increased the positive relationship between relationship commitment and personal referrals; i.e., WOM (Lacey, 2009). Program membership did not influence other variables, including personal information sharing, market research support, and openness to firm promotions. Hospitality studies indicate that program members who possess attitudinal loyalty also have higher behavioral intentions (Mattila, 2006; Sui and Baloglu, 2003), although neither study compared members to non members or investigated tier level. Taken as a whole, the research suggests that behavioral intentions should increase as a function of reward tier.
