My bf and I borrowed a Trico Iron Case a few months ago from one of his buddies for our trip to Georgia for the 6 Gap/3 Gap. http://www.cyclingreviews.com/reviews/iron_case.php

It worked like a charm and we only had to take off the wheels and handlebars to fit my bike in. (Everything fit in the case) His buddy that we borrowed it from usually packs his and his wifes bike in it. That takes a bit more time though, since you have to take off more items and arrange them more carefully, etc.

The only negative thing is the weight of the case. Which is a little heavier than expected.

It costs us $80 to put it on the plane (Continental), and it only cost ~$40 to ship via FedEx from Florida to California.
