You should check with your airline.

https://www.tsa.gov/ The TSA website can help you choice what you can pack and what you can't. I hope you have a safe and happy trip. Also Happy New Year.

Try not to bring any liquids on board. In baggage you can keep all the Custom cleared necessasities for your own use in Morroco.
