How much is a plane ticket for a dog?

It really depends what kind of pet how big the cage is and where you're going and with which airline. I recently shipped my cat from Canada to the States. I had to make sure that the flight connected to another flight of the same carrier/airline (or affiliate of) in order to not pay the rate again. From what I saw in research was that it cost about 100$ for a sm/med cage. If the flight is not direct and there is a layover or next day flight you must also think about boarding your pet overnight. The cost to me was approx 350$ after all was said and done (flight, overnight boarding, flight).
