Shipbikes.com is good and their special box only requires you to remove the front wheel--I know folks who have used them, but I never have.
I usually rent a plastic case from Bicycle John's in Burbank for $65 a week and take it on the plane. Cost $50 each way with most airlines, but with a couple of tools I can put my bike back together in about 15 minutes. Usually have to remove bars and stem (but leave all cables intact, of course) and then I remove the seat and post (together), and undo the the rear derailleur hanger and cable tie the unit it to the frame. All the parts go into the box, along with tools, pump, helmet, extra towels and rags. Reasonable for a trip longer than a few days, and it's cheaper than renting a good quality CF roadbike.
