Heathrow has announced a major terminal shake-up that will separate transatlantic joint venture partners Delta Air Lines and Virgin Atlantic. From 2028, Delta moves from Terminal 3 to Terminal 4, along with Finnair and Japan Airlines, while LATAM shifts to Terminal 2 and China Southern moves into Terminal 5 alongside British Airways.
Virgin's CEO Corneel Koster has been vocal, arguing the split will create friction, weaken competition and reduce choice. On paper it looks odd: BA and China Southern, already joint business partners, get co-located, while Delta and Virgin lose their shared home. Delta operates roughly 10-11 daily flights at Heathrow versus China Southern's 2-3, so capacity and scheduling logic may explain the difference — but the airport hasn't fully made that case, and the optics of favouritism are hard to ignore.
The practical impact is mostly about the ground experience rather than flight connections. Delta and Virgin sell a combined schedule from one terminal, and eligible passengers can use Virgin's famous Clubhouse regardless of which airline's plane they're on. From 2028 that shared premium experience breaks down. Rebooking during disruptions also gets messier — Heathrow has no airside terminal transfer, so switching terminals means re-clearing security. That said, the two airlines' transatlantic networks overlap heavily, so genuine Delta-to-Virgin connections are relatively rare; Virgin's point-of-difference lies in destinations like India, South Africa, Lagos and newly added Seoul.
Counterpoints exist, though. American Airlines and BA aren't fully integrated either — American has been consolidated in Terminal 3 since 2022 while BA straddles Terminals 3 and 5, so plenty of oneworld passengers already endure terminal changes. And Finnair and Japan Airlines, both BA partners, are being pushed further from their Terminal 3 allies too, so this isn't a clean win for BA's whole alliance. Terminal 4 also isn't the write-off it's often painted as: Delta will sit alongside joint venture partners Air France and KLM, and Air France opened a smart new lounge there in July with nearly 150 seats. Finnair and JAL premium passengers will gain access to the well-regarded Qatar Airways Premium Lounge, though economy flyers who used Terminal 3's Cathay and Qantas lounges via status will feel the loss.
Heathrow's defence is that the reshuffle relieves congestion in Terminal 3, requires the fewest airline moves and the least capital spend, and has the backing of airlines representing 81% of passengers. Sky News reported those airport sources' claims, which are reasonable on their face — though passenger-weighted support doesn't guarantee fair treatment of smaller carriers.
Why should travellers care? If you're booking Delta or Virgin long-haul via Heathrow after 2028, expect separate terminals and don't count on the shared Clubhouse perk. Premium passengers lose the most; economy travellers probably won't notice much either way, since all Heathrow terminals are crowded and pricey. The China Southern move into Terminal 5 keeps the favouritism debate alive, but the story is more nuanced than BA quietly winning.
