Name Change but Real id Required before Wedding Day?

Some other options are available rather than a state-issued "Real" ID. You can have a passport instead. You just have to be passengers identified for travel sufficiently and consistent on the travel papers. It is only areas controlled by the federal government that this requirement exists to ID yourself to their satisfaction. This is the information I have consistently found.

You can then do name changes at your leisure after the wedding events and honeymoon.

Agree with this. Particularly because your ID has to match your flight ticket and names on tickets can't be changed. Get your Real ID now, book your flight with your current name and use your current passport for your honeymoon. Replace everything after you return. You can still file your name change with the department of social security in the meantime, that is the first step anyway so it won't even necessarily slow down the process.
