Yes, alcoholic and non-alcoholic drinks are completely free in British Airways Premium Economy (World Traveller Plus) in 2026. This service is a premier step up from standard economy, beginning with a high-quality pre-departure beverage (usually orange juice or water) served in real glassware once you are seated. Throughout the flight, you have access to a full complimentary bar service that includes signature cocktails, mocktails, a selection of wines (typically two reds and two whites), spirits, and beers. Flight attendants are often proactive in offering "doubles" or extra refills compared to the standard cabin. For 2026 travelers, this "elevated" dining experience—which also features two high-quality meals served on chinaware—is one of the most high-value reasons to upgrade, as it ensures a frictionless and more luxurious long-haul journey where you never have to worry about the cost of a celebratory gin and tonic or a glass of wine with dinner.
