On my most recent DL ATL-DCA flights, there has been an announcement that the skies are angry that day, my friends, and FAs will have to remain seated until the coast is clear. On a flight of this length, that has the potential to negatively impact beverage service. FWIW, on all three flights service in first seemed to continue as normal - the FA was up and about the whole flight (and bravo to them for that). In Comfort+ or whatever it's called now, FAs did manage a quick beverage service each time so I got one glass of wine out of it. I assume service in coach was extremely limited. The flights themselves never seemed to be particularly turbulent (and as one who sees turbulence as adding a little spice to a trip, I say that in my most disappointed voice)...

(Also FWIW I don't yet have mega-status on Delta or even mini-status, really, so I'm not one to get showered with upgrades - FCM is generally very reasonable, but with drinks gratis in Comfort Schmumfort or whatever it's called now, there doesn't really seem to be much point to paying to upgrade - but if hyper-vigilance over mean-girl clouds starts messing with the free drinks in Extra Special Comfort or whatever it's called now, that whole calculation goes out the window, presumably into possibly very rough air, maybe.
