On British Airways, the jump from Economy (World Traveller) to Premium Economy (World Traveller Plus) is significant. Premium seats offer 7 inches of extra legroom (38" pitch vs. 31"), a wider seat with more recline, and a dedicated footrest. You also receive a much larger entertainment screen, noise-canceling headphones, and an upgraded dining experience served on real china rather than plastic. Logistically, Premium Economy includes a double baggage allowance (two checked bags) and priority boarding (Group 3). While it does not include lounge access, the separate, smaller cabin provides a much quieter and more exclusive atmosphere than the crowded standard economy section.
