I need to go back to Shanghai from Montreal at the beginning of May and return at the beginning of June. I asked some agencies and they told me there was no tickets left before the mid-May. I am really panicking now!!! Who can help me???? Any phone no? Any tips? I dont have U.S visa, so I cant really book airlines that fly through the U.S, can I? Please write to magicalhands77@yahoo.com
