Bac, it only goes in one way... as shown here:

The most critical placement is of the maintube to the upper right corner. That end is actually above the top of the lower part of the suitcase, but the top part has enough clearance.

Remember to include a picture (even from the link) of how the bike is packed for TSA/security. My packed Swift has been inspected every time I have flown with it.
