mosquito, the Swift goes into an nFlite suitcase ONLY one way, shown on the Swift website.

The key orientation is that the QR end of the maintube must be on top, pointed NNE, with the crank under and on the right side of the suitcase. I also take the pivot bolt out of the RT/maintube joint, and use a master link chain. The handlepost and bars lay on top of the folded frame, and the front wheel as the crown of the pyramid. Seatpost along the long edge of the suitcase, with the saddle removed. Use mylar, bubble pack, cardboard, etc., to separate the layers. There's enough room for shoes, tools, etc.

ALWAYS put a picture of how the bike is packed on top of the "pile", under the suitcase straps. TSA will seriously f**k it up without the pix, e.g., cannot close the lid so they tape the gap with loads of TSA tape. I put numbers on cardboard sheets so if TSA does more than lift and peek, there's a good chance they can get it back together.
