On the other hand, the impact of ‘‘social risk’’ was negligible to ‘‘overall risk’’ in the present study. This result is consistent with previous studies that social risk is not a significant risk dimension in purchasing airtickets online (Cunningham et al., 2005; Ueltschy et al., 2004). This may be because air tickets are not socially desired goods that reflect self-image (as are jewelry, cars, and homes), which are subjected to the opinions of reference groups.
