On Wednesday 2/25, into BNA, we had free drinks in Economy Comfort. FA happily announced to us that it started that day when she arrived with the cart, and many of us did partake. Pretzels as the snack. I did ask for a 2nd, FA agreed and said she would be right back. She didn't return until final, when she apologized and said they ran out of gin. I think there were some high maintenance passengers farther back that were taking up her time, based on a great deal of back and forth plus inventory coming back from the front.
On Friday 2/27 out of BNA we were not specifically offered free drinks in Economy Comfort, but as a "Delta Forum SkyDrunk" I asked and was given one. No indication that I could have requested a refill but I also didn't ask. Pretzels, again.
I don't particularly like that my upgrades aren't clearing like they used to, but at least the free booze takes a small amount of the edge off IMO.
