London Heathrow will soon welcome four new long-haul airlines: Air Peace, Alaska Airlines, IndiGo, and Riyadh Air. Starting late 2025 into 2026, these carriers will connect Heathrow with cities like Seattle, Abuja, Delhi, and Riyadh. Heathrow’s limited slots haven’t stopped these airlines from entering via partnerships or route strategy. As competition grows, these new routes reflect Heathrow’s evolving role in global connectivity despite ongoing slot constraints.
