I'm not a frequent flyer (or I don't use to bring with myself the guitar on business :D) yet I have sometimes to take the instrument with me travelling on trains. The standard cases are good, yet they're better to keep an instrument in safe condition from humidity etc, because you always take some hurts on the cage and they're not eternal.
PROs
This one seems eternal, a huge, heavy battletank, While it's e great choice for travelling, it's also good for keeping the instrument in safe condition when not using it or storing it. I used to keep the instrument in this case while I had to do some masonry works at home and dust during those kind of works enters everywhere. Not in this case, so I can guess it's perfectly sealed (good since in flight the temperatures maybe affecting items).
The handle is well made. The case weights a LOT, so the grip is made to reduce the stress on the hand.
CONs
The only negative side, is the weight. But I see it as a necessary thing.
So, the case is a really good one, both for protecting a valuable item from damages than for keeping an instrument in safe condition if you're not going to use it for sometime.
