Southwest, American, United, Continental, Delta, JetBlue, and others allow cats to travel in the cabin if they have health documentation and can fit in an underseat carrier. The fees are usually somewhere between $75-$150 and may count as a carry-on item.
Thanks so much for all the info,
Locutus! I've been checking carrier dimensions and seat dimensions. I didn't know United allowed pets so that helps. I've been doing all this research too but you're so much better at finding it and presenting it!
By the way, if this move goes through we'll be living in the same state! Don't worry, I'll be far enough away.
I'm almost certain you can't take animals into the cabin with you.
I've been on flights where people had animals in the cabin. The carriers they used were similar to the ones pictured
here.
Yeah, I'd get a soft-sided one so that it can conform to the dimensions a bit. I've never actually seen people bring pets in the cabin but I know that it's done.
"Cats on a Plane"? I'd watch it.
I was *this* close to making that the title of my thread.
Well I just heard about this new airline called
Pet Airways. They are a pet only airline, and they call the animals their "pawsengers."

It looks like it would cost something around $400 to fly your pet across the country. They only service the major cities I believe.
I looked into that too, but the nearest city would be LA and that's probably a good six hours from where we'll be.
What about fellow travellers with cat allergies?
I would be most displeased to be stuck next to a cat on a cross country flight.
As would I.
That's something I've considered as well, which is why I'd much rather have gotten a cabin on a train even if it was much more expensive. While I'm sympathetic to those who suffer from allergies, I absolutely will not put him in cargo if it comes down to that. I wouldn't have him out and about during the flight and people carry a lot of animal dander on their own clothing, honestly.
No I've been reading, some airlines allow it and some do not.
This would help me choose which airlines NOT to fly.
And that's a good idea. If it's something you feel strongly about, their are obviously other airlines to choose from.
I'm sorry if I'm not coming across as more sympathetic but I really just want to find a way to move my cat safely across the country. It's not like I'm taking him on some vacation because I can't bear to leave him behind. This is a one-time thing and I'm generally stressed about the idea of relocating, given that I've lived in IL my entire life. I'm just trying to find the quickest, safest way of doing it all.
