Our cat is the same. We used to drive 2 hours every other weekend to visit my father. I found that she was much happier being held on my lap (or in a shallow cardboard box which I placed on my lap) than in the cat carrier (YMMV). I used an aluminum pie pan to catch the inevitable barf, and sopped it up with a paper towel and put it in a plastic bag to be disposed of upon arrival. I got so I could tell by her gurgly meow that she was about to explode, and could grab the pan and put it under her chin with about 10 seconds notice. She seldom repeated the performance -- until the next trip. She never came to like the trip, but we were happier.
