Ummm..... sounds like the dog got first class treatment. Did you make your sister walk home?
My sister much rather walk home
then get in any plane much less my plane!
Actually reason I took the dog is that we felt that a 1 1/2 hour flight was better for Koko then a 6 hour drive to SC where she was to spend some time with her inlaws (dog will be 15 years old this year).
I have a 20 second video of her (the dog, not my sister walking home) on my You Tube channel (no ATC COMS) and you can see she is clearly enjoying the flight. This was her 5th flight.
