Check with the airline first. I usually fly US Air and they allow me to bring Diamond but I have to pay $80 EACH way and she has to sit under the seat in her carrier/crate. You are not allowed at any time to bring her up on the seat with you.
I thought $160 was A LOT to take Diamond with me. I have a really good petsitter here in Virginia that takes care of Diamond on weekends when I have to fly home and when I drive, I take Diamond with me.
Where do you live or where would you need the petsitter? I am sure there is a petsitter in your area. Try
www.petsit.com
I used it to find my petsitter and most of the sitters come with high recommendations from other clients and some are even licensed. Good Luck!
