A lot depends on the country you are travelling to. Australia is just one country that is very strict on animal and plant imported through customs. Check with the airline - though I would not attempt it. The nuts may be confiscated and you could suffer a fine, not to mention a very long delay before you can get through customs.
================================================
For a while, some airlines designated some flights as nut-free due to customer Allergies. I do not know if they still do that, but checking with the airline is always a good idea.
Yes. As long as your duffle bag is within the airline's size requirements for carry on luggage, you can use a duffle bag as a carry on item.
You can pack them in your checked luggage, but you cannot bring them with you on the plane, such as in pockets, purse, carry-on bag, etc.
If your going onto a road trip, yes, but if you are going on a plane you can bring it with you but you cant bring it in your carry on but you can put it in the bag that will be under the plane.
Yes, but check that it hasn't got attachments that could be considered dangerous.
Some airlines allow you to bring 7 kilos to 10 kilos of carry all bag, how about in British Airways? What is the weight to bring as your hand carry all bag?
u cant bring hookah tobacco in a travel carry on bag because u can faint
Hahaha, no!
Can't say for certain. It depends on how big the carry on bag is and what plane you are on.
Yes, you can take a backpack on a plane as carry-on luggage as long as it still fits the size and weight restrictions for carry-on baggage.
Only a ski mask
No it is not allowed on a carry on but it is allowed on a checked bag or suitcase. If I were you I would put it in a plastic ziploc bag incase it cracks.
If you're carrying it onto the plane, it's a carry-on bag. You are allowed one bag that fits underneath the seat and one additional small bag that fits into the overhead compartment.
