I’ve successfully signed up for the CA DMV Wallet app, and have a QR code representing my driver’s license. Additionally, I’ve been flying with mobile QR code boarding passes for years now without problems.

Will I be able to successfully board a plane from LAX without using my physical plastic driver’s license, or a paper boarding pass?

I’ll resolve this YES once I’m sat in my seat on the flight.

I'll be flying out of Terminal 3 (Delta) on the afternoon of Friday, April 5th. This article says that it should be possible: https://www.tsa.gov/news/press/releases/2023/12/15/tsa-accepting-california-mobile-ids-identity-verification-lax

I am only counting the flight out of LAX, as I don't believe my domestic destination supports paperless.

I have TSA PreCheck.
