Perhaps you are considering a crossbow hunt and need to fly to your destination like me.  I have booked a 2025 trophy spring black bear rifle/crossbow hunt in Alberta, Canada.  I will bring my 10 Point Turbo S1 Crossbow along. Hunters in Alberta are allowed two bears.

I went online to look for a hard crossbow case.  This case below is said to fit all 10 Point Crossbows since 2019. The cost was $250, a bit high. However, the case was designed for specific 10 Point crossbows. The internal dimensions allow similar crossbows with varying fit quality like mine. 

 Ten Point says the case is hard enough for air travel, as a checked bag, but must have TSA airline approved locks. The case does come with some protective foam. I have added more. The case also has some exterior connection points for strapping to an ATV. 

Some air-traveling  crossbow hunters suggest to keep arrows and broadheads separate in other checked luggage. We shall see. I purchased a broadhead case from Muzzy below for $10.50. Keep those blades razor sharp. 

Fly Safe.
