Ah, my bad. Just re-read and realized you're shipping your dog TO Grenada.
In that case, look online at Amerijet.com - the schedules are posted clearly for all to see. You will have to drop off your dog the night before, usually between 7-9pm but they will tell you more specifically. Call the 800 number and speak to the Live Animal Coordinator, who is very helpful. Those guys are good in Miami, my puppy has traveled with them 3 times and it's always gone beautifully. Good luck!
