Contact your airline to discuss its baggage policies. Most airlines have strict size and weight restrictions when it comes to what you can bring on the plane. Heavy or oversize bags can be allowed on for extra fees. There will be size and quantity restrictions for carry-ons as well. Figuring out your baggage fees ahead of time will help you stay within your production budget. It will also help you to determine which gear to check and which to carry on.
Discuss your "excess valuation" options with the airline. Though not openly advertised, many airlines will cover up to $5,000 for lost or damaged valuables. However, this must be declared in advance and is usually subject to a relatively small fee.
Purchase travel-safe cases for all your gear. Though the storage cases you currently use may seem pretty sturdy, they may not be designed for tumbling around in cargo holds. Ideally, you want cases that are hard plastic, watertight and lined with impact-absorbing material.
Lock up your gear with TSA-safe luggage locks. These combination locks have a special keyhole on the bottom designed for a TSA master key. Keeping your gear under lock will keep your gear safe while still allowing airport security to get in if need be.
Remove any light bulbs from the gear going with your checked luggage. These will be much safer in your carry-on.
Pack film in your carry-on bags. The scans used on checked baggage can ruin film. Be aware that any film going through the security checkpoint will likely be checked by hand. Pack it in a plastic bag and remove it from your bag before sending your carry-ons through the scanner. If you are using a digital camera rather than film, your memory cards will not be affected by either scanning method.
Arrange transportation to and from the airport in advance. Airport shuttles and taxi cabs will likely not have the space to store several large cases of video equipment.
Talk to the security agents regarding your equipment. If your carry-on baggage is selected for a random search, explain to the agent that you have delicate camera equipment in your bag. Though they will still need to examine the equipment, they will do their best to be mindful of your equipment's safety.
