London Heathrow is planning a terminal reshuffle due in 2028 that would move Delta — along with Finnair, Japan Airlines, LATAM and China Southern — out of its current home. Delta and fellow SkyTeam partner would go to Terminal 4, LATAM to Terminal 2, and China Southern to Terminal 5, while Virgin Atlantic and American Airlines stay put in Terminal 3. British Airways isn't moving at all. All told, the five displaced airlines represent only about 3.5% of Heathrow's departing seats, but the change stings for premium passengers.
The headline loss is lounge access. Delta business class travellers currently enjoy Virgin's Clubhouse in Terminal 3 — long one of the best business class lounges at Heathrow, famous for its playful retro-British styling — plus the separate Upper Class Wing check-in experience. From Terminal 4, none of that is on offer. Finnair and Japan Airlines passengers face the same problem, losing Terminal 3's unusually rich lounge line-up, which also includes Cathay Pacific's first class lounge, Qantas' lounge, American's, British Airways' and the Amex lounge.
Virgin Atlantic has pushed back hard, with CEO Corneel Koster arguing the split would create customer friction, weaken competition and push up fares, and the airline is weighing ways to challenge the decision. Sceptics aren't convinced. Delta and Virgin already operate a largely point-to-point transatlantic model — Virgin's short-haul feed at Heathrow is thin compared to British Airways' European network — and American passengers already make the Terminal 3 to Terminal 5 transfer with BA routinely. As for higher fares, a weaker product arguably means less pricing power, not more.
The real driver appears to be capacity. Terminal 3 is under strain on gates, stands, seating and baggage handling, and the proposed reshuffle reportedly involves the fewest moves and least capital spend. British Airways has reportedly backed it, partly because China Southern would land in its Terminal 5 home. Virgin moving to Terminal 4 alongside Delta was considered, but would have forced other airlines out and left a gap where Virgin's premium facilities sit.
If you're flying Delta or JAL to Heathrow after 2028, the practical takeaway is to set expectations: the Terminal 4 lounge scene doesn't come close to Terminal 3's, and terminal transfers at Heathrow can be slow — one writer needed three buses and 95 minutes to cross from an arriving BA flight to a Terminal 4 lounge. Time connections generously.
