Delta Air Lines CEO Ed Bastian has strongly criticised Heathrow Airport Limited’s decision to relocate Delta’s operation from Terminal 3 to Terminal 4, separating it from transatlantic joint venture partner Virgin Atlantic, which will remain at Terminal 3.

“Heathrow Airport Limited’s decision to relocate Delta’s operation to Terminal 4, away from our partner Virgin Atlantic, is short-sighted, deeply disappointing and bad for airline consumers. For more than a decade, our airlines have served millions of customers through our co-located operation in Terminal 3, offering travellers convenient connections, premium amenities and access to an expanded global network,” Bastian said in a statement.

“Delta and Virgin Atlantic provide UK consumers with a valuable competitive alternative across the Atlantic. Separating our operation undermines years of investment and disregards the tightly integrated customer benefits that we offer in our co-located terminal. We are committed to preserving the seamless travel experience for which Delta and Virgin Atlantic are known and will pursue all available remedies to correct this decision. We urge Heathrow Airport Limited to reconsider their decision in favor of a more prudent and thoughtful outcome that puts travellers first and allows competition to flourish at Heathrow,” he said.

THE WIDER TERMINAL REALLOCATION

Delta’s statement does not itself explain Heathrow’s reasoning, so WAN has sought independent confirmation of the background. Heathrow’s move affects five airlines as part of a terminal occupancy review the airport says has been running since 2023: Delta, Finnair and Japan Airlines move from Terminal 3 to Terminal 4; LATAM moves from Terminal 3 to Terminal 2; and China Southern moves from Terminal 4 to Terminal 5, joining British Airways under their joint venture. Together, the affected airlines represent a small share, reported at around 3.5 per cent, of Heathrow’s annual seats. The moves are reported to take effect in 2028.

Heathrow has been reported as saying the changes are intended to make better use of terminal capacity and to ease congestion at Terminal 3, the airport’s oldest terminal, from which three airlines are moving with none moving in. Heathrow has also been reported as saying that airlines representing 81 per cent of its passengers support the final decision. The practical effect is to place Delta alongside fellow SkyTeam members Air France and KLM at Terminal 4, while Virgin Atlantic, which is not a SkyTeam member, remains at Terminal 3; a Delta-Virgin Atlantic connection at Heathrow would in future require a bus transfer between terminals.

Note: Heathrow Airport Limited had not, at the time of writing, issued its own press release addressing this decision in detail; its reported position above is drawn from on-the-record statements to UK aviation and travel media rather than from a Heathrow primary release, and is presented here for balance alongside Delta’s own statement, which is the primary source for this article.
