Can you take a backpack cooler on a plane?

After looking at the TSA website and Delta, it looks like taking a cooler on board as a personal item should be fine. My cooler is a similar size to yours, and I've seen purses that are just as big! I think as long as it will fit at your feet, it's ok.

Chill the Cooler Before Packing A cold cooler keeps ice longer. If you somehow have access to a commercial freezer, let the cooler spend the night inside. For everyone else, keep it out on your porch overnight, or stick it in the coolest part of your house the night before your trip.
