On British Airways, the difference between World Traveller (Economy) and World Traveller Plus (Premium Economy) in 2026 is substantial. Premium Economy offers a much more "human" experience, featuring 7 inches of additional legroom (38-inch pitch vs. 31-inch) and wider seats in a separate, smaller cabin. You are also entitled to two checked bags (vs. one or none in basic economy) and priority boarding (usually Group 3). The dining is significantly elevated, with meals served on real china with metal cutlery, often including a choice of dishes from the Business Class (Club World) menu. Onboard, you'll find larger 12-inch entertainment screens, noise-cancelling headphones, and a dedicated amenity kit. For 2026 travelers, the "pro-tip" is that the price is often double that of economy, but for a long-haul flight, the combination of sleep-ready recline and quieter surroundings makes it a very popular middle ground.
