I have tried a couple of known web sites to book a flight from Toronto, Canada to Changchung, China and no matter how many times or days I try - I end up seeing the friendly message below. I mean, do their service have any built-in intelligence at all? I had the same experience half a year earlier so there's something fundamentally wrong going on. Needless to say their customer service does not explain why they fail to deliver the major service they offer - selling flight tickets. Does any one know what is up with that? Thanks
