Not recently, but I remember easily over a decade ago when Song was still flying, I flew on a flight from PBI to LGA. Because of a long weather delay, the Captain came into the gate area and gave a speech about flight plan, runway use, etc. and continued that in the air (specifically referencing that we would be flying the Expressway Visual for Runway 31 at LGA). Haven't seen that much lately on Delta. I had a JetBlue Captain who did that because weather along the normal route of flight meant we were flying a longer routing that was not common for that route.
