There is some really bad advice in this thread. Any warrant anywhere is potentially a serious problem and can lead to being detained in custody --- what we call the hoosegow --- for at least a period of time if not longer. Often it is not about the seriousness of the offense, but that you disobeyed a court order and those are sometimes considered serious. Do not get your back up about the system. If you want to defy a court order, so be it. But, do understand that there are consequences. There are ways to challenge convictions, sometimes, but one of them is not to simply ignore.

First, the advice that misdemeanor warrants cannot be extradited from one state to another is false. It is simply that most state and local jurisdictions do not want to spend the money on extradition and therefore do not extradite. But, most enter their warrants in their state warrants system and some of those systems enter the information in NCIC. While you may not be extradited, you may be detained or arrested until it can be confirmed that you will not be arrested.

Second, some of the warrants described in this thread are "bench" warrants issued by a judge for failure to appear, pay a fine, or do something else. Not all are extradited, some are.

Third, it is unlikely that bounty hunters are out looking for you on minor charges. But, if law enforcement has a reason to run your name, the warrant may well show and you will be detained for extradition until it can be sorted (and perhaps not sorted). As the example above shows, people are sometimes dragged back in custody for things they thought were long gone.

For the specific question about traeveling to ATL for necessary business when it is impossible to have the warrant dealt with prior to travel, you have no option but to travel, so go ahead. Don;t give anyone a reason to check your record, including motor vehicle stops and you will likely be just fine. But, don't take this as a guarantee because it is not.

For others with minor things such as unpaid fines, just pay the fine. That is the easiest and quickest thing to do. Then, make certain that the warrant has been recalled and that the court has confirmation that whatever law enforcement agency it works through for the entry of warrants actually has done the entry. For even minor stuff, it may be easier and better to retain a local attorney who knows the system and how it really works, to make certain that all of this is done.

What happens to one person at one place has no bearing on what happens to another at another place.
