Seems like most cost savings under the guise of sustainability and virtue signaling. I don't see details in this post but I'm not sure how they plan to be "more sustainable" in their wine offerings -- I suspect it involves saving money.
Sadly par for the course for DL these days
EDIT: Here is the wine update. Appears to be for domestic Y consumption -- replacing single-use plastic bottles with canned wines. Meh -- okay, domestic Y wines aren't anything special so the bar is pretty low for this change to be neutral or better.
Delta will now serve two new aluminum-canned wines from
Imagery Estate Winery, a premium Sonoma winery led by award-winning winemaker Jamie Benziger. In 2019, Jamie was named Best Winemaker at the International Women’s Wine Competition and named to Wine Enthusiast’s 40 Under 40 list.
Delta will offer Imagery’s Cabernet Sauvignon and Chardonnay onboard starting with select coast-to-coast flights this month and will expand to all domestic flights later this year. The wine’s aluminum packaging reduces annual plastic use by up to 250,000 pounds. Imagery’s wines are also sustainably grown, as certified by the California Sustainable Winegrowing Alliance.
And apparently Y is getting bamboo cutlery instead of plastic cutlery.
