Can i book a flight with a warrant?

I would handle the warrant before i travel anywhere

Interesting question. Probably. How would they know?

The best thing you can for yourself is to avoid attempting to sneak in and out of your State or country. Not all airlines check passenger name against certain database for domestic flights, specifically databases that might provide a list of individuals with outstanding warrent. The security procedure for international travel do involve checking databases. if you are travelling internationally, it is possible that your name will show up in an airline security database.

You should take care of the warrant and not take a Chance of spending your vacation in a jail

Do it and we'll find out 😂
