I called one airline (Continental), and they said they allow 2 animals TOTAL for the entire flight. But, I'll be going to Alaska during an off-season sorta speak ...and can go any time/day within a certain time frame. So, I feel confident that there will be a flight open w/no animals. I figure the people in Alaska mostly want to bring over their BIG dogs in the back cabin anyway (which don't count towards in-cabin).
She falls a few oz. below the max weight limit (cat), which is good.. but the back cabin seems like the most ideal since ...there's probably cat litter involved? Not to mention, she's a meow'er unless I stick my finger in the crate the entire flight.
She probably has the least amount of anxiety among our animals. The back cabin doesn't scare me, as I trust the airlines, and know how many thousands go every year.... it's just the comfort of our cat I'm worried about when it comes to dying to pee/toot. They temperature should be perfect before take off (before they regulate the temp).
