real id – Is my US Drivers License valid to board an airplane?

In May, I received a new US State Drivers license. This Driver’s license is not a Real ID, and is marked with NOT FOR FEDERAL IDENTIFICATION. According to TSA RealID Info I believe that this License is valid to be used as identification until 2023.

If I go to a US-Domestic airport, will this Identification be accepted?

How would I find out for sure?

(Background, I also need to renew my passport which is my primary form of identification when boarding a plane. I would like to renew it soon, but then I won’t have it for my next few flights that are coming up).
