As of December 14, 2016, Delta will offer improved snacks in Economy on all flights over 250 miles. Gone are the amusingly-labeled pretzels and peanuts, replaced by Snyders of Hanover pretzels, Squirrel Honey Roasted peanuts, and NatureBox Apple Cinnamon bars. The Delta Biscoff cookies remain (thankfully).
Delta says that the improved snack selection was a result of customer feedback, and that moving forward, snacks will be changed out more often. These upgraded snacks are a step above what other legacy carriers offer in economy.
Vending machines in NYC, LAX, and SEA will offer Delta fliers complimentary samples of the new snacks.
