Purpose: Social media (SoMe) influencer marketing is a popular practice. The current study examines the interplays between SoMe influencers' source credibility, Millennial users' attitudes and intention to travel. It further investigates the moderating role of SoMe influencer following behavior on the aforementioned relationships.Design/methodology/approach: A total of 212 useable responses were collected through an online survey. Structural equation modeling and hierarchical multiple regressions were employed for hypotheses testing.Findings: Results indicated that source credibility had a significantly positive influence on the SoMe users' attitudes, which in turn was positively associated with the intention to visit the endorsed destination. Moreover, both relationships were strengthened for SoMe influencer followers than for nonfollowers.Originality/value: The study expanded the source credibility theory to the use of SoMe influencer marketing on travel destinations among Millennial SoMe users. In addition, the research applied the self-determination theory to fill the gap in literature by examining the moderating role of SoMe influencer following behavior.

Understanding how green hotels can gain marketing advantages could motivate hoteliers to adopt green practices during construction and operation. This study investigates the mediation role of perceived psychological benefits on consumers’ environmental concerns and their willingness to pay a measurable premium for green-label hotels. Data gathered from 540 Chinese consumers revealed that a mismatch between the involvement of hotels and online travel agencies (OTAs) hampers the relationship between environmental concerns and perceived psychological benefits of booking green-label hotels on OTAs, further influencing consumers’ willingness to pay a premium. This research uncovers an overlooked but crucial factor that reduces consumer satisfaction with the hotel-choice process and why it makes consumers willing to pay a premium for green-label hotels. Drawing from the findings, recommendations are also proffered for hoteliers to conceive and execute green marketing tactics.
