Question: What size is it and is it UPS legal?
Document: Good in size, but built in a little fragile material... It's not safe in airplanes, if they put something on the case, it will break the bike!
I bought this case from Preformance Bike. It is their "Team" case and it appears to be the same B & W case listed here on Amazon. The Preformance case is made by B & W and did not include separate bags for the wheels (whatever). Have shipped it once via UPS and once via Southwest Air. It cost $125 UPS with the extra $3000 of insurance and $50 Southwest for the oversize.
The hinges are the only structures that connect to two halves of the case (upper to lower). The hinges are connected to each case half by rivets. The hinges themselves are tiny, about the size of a standard post-it note and are very thin. Each hinge half (half a post-it)is connected to each case side by the rivets. The rivets themselves are also very tiny, about 1/4" head diameter, and look aluminium.
Turns out that these allow one case to nest on top of another, so that when piled in a van, the top cases do not slide off of the case on the bottom. And given the construction, we had no concerns about stacking these four cases high (check with the manufacturer for correct stack limits).My only niggle is with the latches that close the case.
This is a great designed bike case. I just purchased and used for an international trip that had 3 flight legs over 10,000 miles. If not for the wacko airline ramp workers and the TSA bozos, the case could be locked and no worries. However because one must leave the case unlocked in the USA, it is difficult to get the latches to align and then snap shut.
The shape makes it difficult to arrange the handle bars in such a way that the wheels fit in without inhibiting the top from closing. I've tried a number of ways, there is no simple way to accomplish this. Inevitably, it take longer to pack than the clam shell cases. In addition, the TSA WILL ALWAYS OPEN A BIKE BOX - I have found that they have a difficult time placing the wheels back in so that the box fully closes.
The rivet and the aluminum strap cover simply ripped apart. As others have commented, the rivets on the bottom show ware very quickly. I suspect the life of this case is short. Looks good, seems simple, however the clam shell boxes are not only simpler to pack they also last  and last. They are lighter too. It's important to keep your total ship weight under 50lb. I have found this case loaded with the bike, helmet and some tools is about 49lbs ( I ride a 52 pinorella ).
The pulling handle on the side of the case is too delicate, especially given the fact that luggage handlers tend to use it as handle to lift the case.
The other negative is that the wheels do not steer. The case will only roll in a straight line. not too swift for a 25-30 lb total weight item that is so bulky. It wouldn't take much design effort to have 2 sets of wheels be able to steer.I still recommend it because there are not a lot of other good choices.
The hand pull is aligned on the top of the case side. It's easy to pull in a straight line with all 4 in contact with the ground. But how often does one travel in a straight line? I find myself constantly lifting the front wheels to realign. Lifting the case and pulling it on the 2 rear wheels isn't an option for anyone under 10 feet tall, due to the high position of the hand pull.Then there are the bottom hinges.
Answer: yes
