My question is related to photography equipment and air travel. When I travel most times I manage to carry my limited equipment (5D 2nos, 3-4 Lenses, 2 Speedlights, memory cards and a laptop) in my tarmac backpack, although carry along baggage limit in 5-7 kgs so far havent been stopped for weight check. I have never put all this expensive equipment in check in baggage as I have been advised not to since check-in baggage is badly handled. My question is what is the best option or what should I do if I have to carry more equipment say couple of more cameras few more bulky lenses , a few go pro, a tripod and an underwater Ikelite housing which is bulky all by itself . It would be really helpful if someone who has been in such a situation guide me on this. What are my options? Im based out in India and most of my travels is domestic. Im not sure if this is the right forum for this question but thanks in advance.
