Will you be arrested in airport if you have a warrant?

AnswerGenerally not, but it depends on the nature of your warrant:

If you have committed a serious crime (such as murder, child abuse, etc) and there is a warrant out for your arrest, most local airports will be flagged with your name/and or picture. HOWEVER: unless you are a well-known felon, generally the only way they will know is if you check baggage. That means that while they might not recognize your name as you go through security etc., I can almost guarantee that the airport's computer system will have your name/driver's license number flagged, and they WILL take the time to check into it. So a safe bet is not to travel at all, because there is no exception to this: leaving the state when you have a warrant out for your arrest is a felony. But if you must fly, check in online or at a kiOSk in the airport.
