I never said it was cheaper to fly them with me, I said that I have left them in a kennel for a long period of time before and it was not good for them. They didn't adjust well. Also, there are no direct flights from Toronto to Santo Domingo, which is why AA booked me on evening connecting flights. You cannot travel with a pet on any airline if the current or forecasted temperature is above 85 degrees Fahrenheit (29.4 degrees C) at any location on the itinerary. My vet said as long as the temperature is below 29 they will be fine.
