I know that identification requirements have changed. Can you please advise on acceptable forms of ID?

Currently, a valid drivers license is all that is needed. Next year, a Real ID compliant form of identification will be needed. Kentucky is updating to that standard, so you will need an updated license or a passport when that goes into effect. Don't know the exact date.

TSA operates security at this and I believe all US airports. The best answer can be found on the TSA website. But my short answer is a valid state picture ID such as KY drivers license or state ID (I've used both at Barkley). A passport also is acceptable.
