Wiwi,did you already order your air ticket? My husband would also go from Guangzhou to Montreal on Dec.4, you could cotact him with his 小灵通: (020)33051285 (David), but he would fly from Guangzhou-Beijing-Vancouver-Montreal.
I booket a seat on Dec. 4. why would your husband go to Beijing first? is the ticket cheaper? It is more convinient to go from HK. My husband is in Montreal. You can contact him by 514-7690601
