Last year, Frito-Lay, Plano, TX, introduced Lay’s Air Pops in the Northeast and Midwest, but this year, the airy crisps head to California and the Pacific Northwest. To recognize the expanded distribution, Frito-Lay also launched a new flavor of the Air Pops: Salt & Vinegar. The new variety joins Original, Barbecue and Sour Cream & Onion. A 3-oz bag of Lay’s Air Pops retails for $2.99.
