My concern was due to an incidence that happened a few years ago. One of our graduate student travelled to San Francisco for a conference and on his return trip back to Virginia, he packed his gear in his check-in luggage. His 1D plus gear and memory cards were gone. TSA "reviewed" the tapes and did not see anything out of the ordinary. So, he lost his all his camera stuff. Sad.
I am very uncomfortable with checking in expensive equipment in my travel luggage, and now, traveling on airplanes are even more restrictive, both check-in and carry on. Some airlines restrict carry on to a certain weight and size.
Hi Lion Rock, I think your right to be concerned.
I find different airlines & different countries tend towards different standards, it's been a bit of a suck it & see.
I typically Carry On 2 x 1Dx Bodies, 1 x 5DMK III Body, 200-400f/4 + 300f/2.8 or 600f/4 + 70-200f/2.8 + 24-70f/2.8, Flashes, additional support gear I check In with my checked luggage, typical carry on weight is 16-18Kgs, a lot more than most allowance. If one of my Lads is travelling with me not such an issue, but on my own the only Airline that I NEVER have a problem with is Singapore Airlines.
Australia, the Nanny State, are hopeless, if it's carry on & over the allowed weight, even if your travelling 1st or Business, you check it, I've had to pull a 1Dx + 300f/2.8 out of a Bag & sling them around my neck to get through as Carry On.
Indonesia, if you state that it's Camera Gear most Airlines will allow you 12 to 15 Kgs, even on checked overweight, if you tell them it's Dive Gear, your generally Ok up to 30Kgs.
Africa, in South Africa they tell you at check in, do not check expensive Camera Gear, having said that I had my worst experience in Tanzania leaving Dar Es Salam on a SAA Flight, Business Class, they removed from me one of my Carry On Bags (I had my son with me so should have been allowed 2 Carry Ons), Long Story short, the Bag never made it to Johannesburg (+ 20k in Camera Gear), luckily 2 weeks later the bag "suddenly" was handed in, this was because I had Politically connected friends in South Africa that threatened Legal Action against the Airline, in Africa it's a real risk to check Camera Gear, very good chance it'll disappear.
My advise is always Carry On where ever possible, book an extra seat for overweight where ever possible (Internal flights in Africa), always always have your gear fully insured.
