You are not allowed to bring pot with you on an airplane no matter where you fly. Only if you are a legal resident with a valid card should you even be in possession of the stuff. It is still a federal law that pot is not legal. You run the risk of being detained or arrested at the minimum. It isn’t worth the risk.
No, you cannot fly anywhere with marijuana. Commercial airports and airlines are under Federal jurisdiction. Marijuana remains illegal under Federal law and the TSA does not respect local law. Where you are flying does not matter as the marijuana becomes illegal as soon as you enter a commercial airport. The TSA may just warn you, but they also could prosecute you.
