Heathrow Airport is considering a terminal reshuffle to optimize space and improve efficiency. Currently, Terminal 5 handles 40% of passengers, mainly British Airways and Oneworld alliance members. Terminals 2 and 3 are outdated, and Terminal 4 faces logistical challenges. The proposed plan involves relocating British Airways and Oneworld partners to Terminals 2 and 3, freeing Terminal 5 for other uses. This could enhance efficiency, reduce congestion, and improve the passenger experience. Future expansion, including a third runway and new terminals, may further benefit passengers.
