Virgin Atlantic warns passengers 'will pay the price' and threatens legal action over Heathrow's plan to split it from Delta

Heathrow plans to move Delta Air Lines from Terminal 3 to Terminal 4 by 2028, splitting it from Virgin Atlantic, which holds a 49% stake in the US carrier and runs a joint venture coordinating their schedules. Virgin Atlantic chief executive Corneel Koster says the relocation would "create friction for customers, weaken competition and reduce choice", and the airline is now considering legal action to block it.
Heathrow is also relocating China Southern, LATAM, Finnair and Japan Airlines as part of a broader two-year terminal overhaul to streamline capacity.
Koster warned that Heathrow is the only major airport choosing to split joint-venture partners rather than co-locate them, undermining a decade-long alliance.
Virgin Atlantic says the Delta partnership provides "the most meaningful competition" to the dominant British Airways-American Airlines joint venture at Heathrow.
