The Luggage Works now handles PNT..
I have both a PNT roller bag and flight case..Both are built like a tank.
Their repair and warranty policy is great but you never need it..
Most of the majors use PNT bags as standard issue..
I have a Travelpro that I have gone around the world about 10 times with. I have had it over hauled about 10 times. The last time I was at Travelpro in Boca I bought a used backup case for $25.00, not a bad way to go.
