If you cant stand being seperated from your guitar for traveling.... Maybe you should look into a Travel Guitar.  They are not that expensive, but they are easy to travel with (fits in overhead bins).  You buy a pocket rocket amp and some headphones and you are set to go.  The headphones make it acceptable to practice just about anywhere.  Great for motels.  I take mine on ski trips where I stay in motels.  I am in there shreading and there are no complaints from the adjoining rooms.  Also a great way to  burn time while waiting for a flight.  You go find an unused gate area and go back in the corner and you can shread to your heart's content.  Headphones mean you can be blistering paint off the wall, all the while bothering nobody.  It really helps to pass that dead time.  I bought one years ago and now I never go anywhere with out it.  Mine took a little while to get used to holding, but attaching a strap solved those problems.
