24 Jan 2023 IAD-SFO AS435 — 5:15 PM — 8:30 PM Estimated departure 7:50 PM
24 Jan 2023 LAX-IAD AS310 — 8:25 AM — 4:15 PM Estimated departure 10:50 AM
24 Jan 2023 SFO-LAX AS1308 — 8:10 AM — 9:50 AM Estimated departure 8:10 AM

My guess is, something else happened with the originally planned plane, and the best option they had was to use N929VA. Unfortunately it wouldn't be in LAX in time for AS310's originally scheduled departure, so that flight and yours got delayed.
