I wouldn't recommend the Freedom case for checking on a flight, although it will probably survive 99% of the time. I have one freedom case for my Lakland Skyline Bob Glaub - it is great for packing in a van, but a little rough handling could puncture it in the airline baggage handling world, I think.
I would recommend either an aluminum Flight case or the SKB Bass Safe - where you load a gig bag in the hard case.
Bass Safe
This only works well if you have a very high quality gig bag that fits snugly in the Bass Safe.
