Hi guys, I booked my ticket to Chicago... my cat's "pet fee" cost as much as my own seat! lol Can you tell me what kind of container you kept your pet in? A soft-sided container or a structured plastic kennel? I don't know what would be more comfortable for the cat and also convenient for me to lug around my stops. The airline's regulations are 17 inches long x 16 inches wide x 8 inches tall. Thanks, everyone.
