I'm not sure why Real ID would be enforced now. This site:

says that non compliant Georgia drivers licenses can be used for air travel until Oct 1 2020
Georgia is compliant with Real ID, so I believe your old license would still be usable.

Starting January 22, 2018, passengers with a driver's license issued by a state that is still not compliant with the REAL ID Act (and has not been granted an extension) will need to show an alternative form of acceptable identification for domestic air travel to board their flight.
To check whether your state is compliant or has an extension, click here. Passengers with driver's licenses issued by a state that is compliant with REAL ID (or a state that has been issued an extension) will still be able to use their driver's licenses or identification cards.
When you renew your Georgia DL, you'll have to have a fair amount of documentation
