One doesn't have to turn the forks 180 at all. A good friend of mine has flown with a larger frame than this and didn't have to.
Removing front fender yes for sure, but the whole process isn't as hard as this fellow is perceiving it, but I realize that for some people it can be very stressful and seem too much work. That's why bike store packing services are a good option. An easy stress free option for those less mechanically inclined.
I have both packed and re-assembled road and touring bikes and still usually use LBS for that work. Nice to have someone else do that work, especially after I have been up well before the crack of dawn to catch a 6:00 am flight.
Frankly, this plan has all sorts of potential logistical problems/SNAFUs built into it (noted by others) that I am having a hard time believing it's real.
