I have this case

Used it to travel from Seattle to Puerto Rico. My carbon bike arrived just fine. TSA did open it but didn't touch anything. I like this particular case because even with the bike, it's still under 50lbs. Some airlines like to stack fees for both oversize and overweight, so if the box is under 50lbs, that's one less thing they can try to squeeze you on.
