Thank you Aquaman!I have called American Airlines and it seems that they are the only ones that can fly large dogs .There are some excluded breeds ::https://www.aa.com/i18n/travelInform...tance/pets.jsp -
We can fly out of Toronto and stop over in Miami provided that the temperature is not below 7Celsius at departure and it is $200 per kennel.There are some planes that will not allow pets in the cargo area :"Checked pets cannot travel on A321S, A321H, A320, A319 aircraft and all flights operated by our regional partner Air Wisconsin"
Hope this helps!
pleased to be of assistance. Yes,indeed America n are recognized as the best for transporting a larger dog in Cargo
