At British Airways lounges, specifically the Galleries Club and First lounges at London Heathrow Terminal 5, breakfast service typically begins as soon as the lounges open at 5:00 AM. The hot breakfast buffet, which features standard British staples like scrambled eggs, back bacon, pork sausages, and baked beans, generally runs until 11:00 AM. After this time, the spread transitions to the lunch service, which includes soups, salads, and hot entrees. If you are visiting the BA Arrivals Lounge at Terminal 5 (accessible after landing from a long-haul flight), breakfast is served from 5:00 AM until its closure at 2:00 PM, catering specifically to those needing a "power breakfast" or a freshen-up after a red-eye flight. The selection also includes continental options like Greek yogurt, fresh fruit, pastries, and cereals available throughout the morning window.
