If you are asking about what can you bring during your flight, then it will depend if first, do you have luggage? If yes then you have a weight allowance as to how heavy your luggage must be. 2nd is that where are you going? Different countries have different rules as to what you can and cannot bring in the country when you travel.
There are no federal regulations against bringing peanuts on a plane. Those with allergies to peanuts should take precautions and bring medical supplies in case they come in contact with peanuts on a flight.
This would really depend on the airline you are traveling with. Each airline has different specifications on luggage limits so you will need to visit their website or give them a call to find out what their policy is.
