It looks like I will have to check some of my photo gear (DSLR; 4 lenses; large-ish P&S) on a flight from the USA to Egypt next week. The airline, Royal Jordanian, permits a single carryon weighing no more than 7 kg; the additional "personal item" cannot be an item such as a bag, or even a laptop carried in hand. I'm struggling to get my carryon (which would additionally include my laptop, portable HDs, and perhaps a portable flatbed scanner, not to mention my wallet and important papers) down to 7 kg. It seems inevitable that, even if I place the scanner in checked baggage, I will very reluctantly have to do the same with some of my lenses, which I've never done before. Beyond providing the lenses with ample padding, does anyone have any suggestions?
