A bit OT, and similar to jolly_ross above, but FWIW: My wife and I have been using Aerus soft cases for our CF road bikes. Under 35 lb fully loaded with bike and riding gear, much easier to deal with on shuttle buses, cabs, and rental cars. Of the last two trips I've taken, I was charged the bike baggage fee only one way out of four.
Here's some info:

It's a bit dated in that the case now comes with frame pads so no need to make your own.
We do put spacers between the dropouts. We use to leave the chains on the big ring (remove RD to prevent bending hanger), but now remove the chains and zip tie a piece of split hose to big ring to protect it and other things from it.
