It works for Full suspension MTB 5 inch travel
I used this case for airline travel from East Coast to Utah. Although it is a pain to drag through the airport, and you have to go to their "special" pickup area because it can't come out with normal checked luggage, it does protect the bike. I always put extra parts and such in the case, but stay below the airlines max weight for the bike and box (usually 75 pounds).
Build your bike in the Motel/Hotel and stash. Sometimes there is a secure hotel storage area for large luggage as well.
Once you learn how to pack a bike (YouTube) it only takes 20 minutes. And your bike arrives with you getting there and getting home.
