Also, there can only be one pet **per row** in the cabin of an airplane! If you can get two pets into one carrier then you can do that but that's the only way you can get two pets to sit in your row. It's expensive too. I think the last time I wanted to take Mikey Fat Cat to Lizard Land with me, it was going to cost something like $125! When we moved to Magnoliaville, we were going to take the two wimpiest kitties in the cabin with us and the airline said that would be OK but we would have to sit in different rows. As a result, we only took the really wimpy kitty in the cabin and the other two kitties and the dog had to ride steerage! Back then it cost about $75 to take a pet in the cabin with you compared to about $40 each for the babies who had to travel steerage. There's not much space under those seats for a pet carrier either!! I have found that it's much easier to sit in the center seat because there's more room under the seat in front of you for the pet carrier. Mikey Fat Cat had her own Sherpa brand carrier. Poor kitty and the carrier would be all squished under that seat! Once the flight got started, I would periodically take the carrier out and keep it on my lap so that I could talk to Mikey. I would even sneak the top open just a bit and give her a scritch on the head and that kept her fairly calm. CiaoMeow >^;;^<
