Yes, alcoholic beverages are almost universally included as a complimentary amenity in Business Class on both domestic and international flights in 2026. This service typically begins with a "pre-departure beverage," which often includes premium options like Champagne or Prosecco. Once in the air, passengers have access to a curated selection of fine wines, craft beers, and top-shelf spirits, often served in proper glassware rather than plastic. Many airlines, such as Air India and Delta, have recently upgraded their collections to include regional wines tailored to specific routes and rare, aged spirits to appeal to discerning travelers. While some regional domestic "First Class" cabins in the U.S. might have more limited selections than international long-haul Business Class, the core principle remains that these drinks are part of the "all-inclusive" premium fare, and you should not expect to pay for them during your journey.
