The cost to fly a dog with you on a plane varies from airline to airline and is also determined by the size of the dog flying on the airplane.
For smaller dogs that can fly in a carrier beneath the seat in front of you the cost is from $35.00 to $125.00 depending on the airline.
If the dog is a larger dog and needs to fly in the cargo area then it could be from $150.00 to $250.00
Before flying with your dog call up the airline you're flying with to get the exact cost to fly your dog on their airplane.
