Domestic Flight USA - Carrying 1 small suitcase, 1 laptop bag and 1 small school bag.?

Can I carry 3 of them into domestic flight within USA and also International Flight? (AirTrans, American Airline and Northwest)Domestic Flight USA - Carrying 1 small suitcase, 1 laptop bag and 1 small school bag.?
I believe you are limited to one carry on (whatever that is as long as it is within the airline's size limit) and one personal bag. (such as a purse or laptop bag)
No, you cannot. The limit is one standard carry-on suitcase along with ONE laptop bag, school bag, etc..



So that means you would have to find a way to fit the laptop and the things in your school bag into one bag. Or you can always transfer the things in the school bag to the suitcase and leave your laptop in it's carrying case. That would make it two bags, not exceeding the limit. I would go with the latter.Domestic Flight USA - Carrying 1 small suitcase, 1 laptop bag and 1 small school bag.?
Northwest Airlines Carry-on Allowance

Be sure to check new requirements from the U.S. Transportation Security Administration (TSA) regarding restrictions to items in carry-on baggage. Visit www.tsa.gov for details.



Northwest allows you to carry one piece of baggage on board the aircraft plus a purse or briefcase or laptop computer or small backpack. The carry-on baggage must be of a size and shape to allow for storage in overhead compartments or underneath the seat in front of you.



Dimensions:



Cannot exceed 45 linear inches (9 inches by 14 inches by 22 inches)



Following the above you will have to put your school bag in the suitcase, and ensure the maximum dimensions are not exceeded.
No, but find a medium sized bag that can fit both your laptop and your school bag inside it. Then you'll be fine.
