I'm not sure if this is the right forum for this question so mods feel free to move.

I am getting married Sept 6. My wife has to go through all of here Airline and hotel programs and change her last name.

We already have a flight booked for November, when she changes her name with Southwest I'm guessing the reservation will also update ?

She is booked as my companion on SW so I was actually thinking of having her wait until after that flight to change her driver license as her last name wouldn't match the reservation or my companion.

I'm sure TSA and SW run into this issue often but was hoping to get some info on how we should proceed with the name changes, new license, companion name change, etc..........thanks
