A very quick welcome aboard PA with estimated arrival time and requisite weather conditions is pretty standard; anything longer than 10 secs or so and people tune out IMO.

If things go south no one wants to hear "I'm sorry" they want to hear what the issue and (in simple terms), what is being done about it, and an update time or new updated arrival time so they can plan. Bonus points if they see lots of movement up front from us or maintenance.

Just IMO.

I don't have anything close to the Capt America swagger so thanking customers directly would absolutely go south and make the national news lol.
