Domestic Travel with Driver's License

So my brother is planning to fly to Georgia in June for a friends wedding. We're from California. Is he still able to do that with his Driver's License? Can anyone list the states that you can travel to/from with a Driver's License, states that you can't, and states that have an extension for Real ID and till when? Thanks!

Your brother should be fine. I flew from California to South Carolina and then drove to Georgia and had no issues. I also used my CA DL.

If your brother have DACA then he can use his EAD for REAL ID States.

I just flew to vegas & back from Texas - no problems.

What us REAL ID?I've never heard of this...
