Don't fill the bottles up to the top so if there is a change in pressure they shouldn't leak. If there is any leakage it will be contained in the bag and not soaked up by your clothes and if your luggage goes AWOL you won't lose full bottles of your favourite frags.
No offense, but this much work really isn't necessary, I fly A LOT, and long distances, just keep it with you, in a heavy duty ziplock or plastic zipper bag in your carry on and it will be fine and no chance of losing it unless you yourself mislay your carry on some how or go nuts and slam it into a wall or something - I have never had an original bottle leak - I HAVE had a decant leak but just once. On that note - gel pens WILL leak, even explode, ball points only unless you want an inky mess someday. I had it happen twice until a Flight attendant told me to NEVER use gel pens on planes - just plain old ball points, since then never a leaky pen.
