This is an excellent idea which will increase the utility of Ctrip by a considerable margin. PayPal insures all transactions up to $500. It will take a while to work but it will massively improve the utility of Ctrip while cutting its costs.
Ctrip has placed a link to its travel site on PayPal’s Chinese language website indicating it hoped to gain a significant advantage not only from being able to attract users who wished to pay for their travel through PayPal but also overseas PayPal users that might be attracted to its own website through the link on the PayPal. In that Ctrip is probably right.
