I am curious...
if there is an X-Ray machine
then why does a person need to cut the zip ties and open the box?
what is so mysterious?
I would think that the two wheels, the frame, and the seat may give a hint as to what is in the "bike box"
but alas no
it is a riddle to the folks at TSA
it is just bothersome to get my baggage and see the very uniform box somewhat askew
to ship the bike box the traveler needs to pay a fee... 100 bucks on United each way
but... and this is a BIG BUTT!
but... they will not insure your package
if it is damaged... it is on you
