Hey Cleo Well when I was shooting on a pro level I would never place my lens or lamps in anything other then Pelican
http://www.pelican.com/
Totally water proof (Nice feature when someone eats lunch outside on your case)
as far as the plane was concerned I never ever carried anything with me. Everything gets placed the pelican and taken to fed-ex or UPS. They wrap it and I insure it. Overnight if needed with an early morning delv time if needed
