Hello,People! I’m Diana Branes. Do you know about the United Airlines LHR Terminal  which allows passengers to bring luggage for an additional fee. Each bag must not exceed 40 pounds and 62 inches in total dimensions (length + width + height). Passengers can pre-purchase baggage online to save money, with fees varying based on the route. Allegiant offers up to 4 checked bags per person. Be sure to check baggage allowances before your flight to avoid extra charges or delays at the airport.
