YVR-MEX-ZIH is the way

Thanks LG....Westjet may have loosened their policy...what follows is something I just copied and pasted......................Yes, WestJet allows dogs on their flights in both the cabin and as checked baggage, with specific guidelines and restrictions. Small dogs and cats can travel in the cabin on most domestic and international flights, provided they meet size and kennel requirements and are booked at least 48 hours in advance. Larger dogs and other accepted pets can travel as checked baggage in a kennel, again subject to size and other restrictions.
