However, problems with baggage management have led to flight cancellations, which in turn has meant a drop in passenger numbers and footfall at the T5 shops.
A spokesman for Harrods, which launched a new mini-department store format at the terminal, said: “Clearly none of us have seen the airport running at full capacity yet. In the short-term, trade has been consistent with our expectations.”
Ted Baker brand communications director Craig Smith said he was pleased with the quality of the retail offer at the terminal, which includes Harrods, Prada, Gucci, Paul Smith, Kurt Geiger and Thomas Pink.
“It’s a unique space and the retail offer is second to none,” he said. “Ted Baker is trading OK and is in line with expectations. There is still a volume of people, but they are not necessarily in the frame of mind for shopping, especially if they are still waiting to get their luggage back.”
Reiss owner David Reiss said: “The store got off to a great start over the first couple of days and we were over our targets, but now footfall has dropped off by about 50% because of all the cancelled flights, and we’re not sure how long it’s going to last.”
The chief executive of one luxury retailer said his store had not seen “any big drama” and that sales had been “pretty good considering”.
Other retailers at T5 include Bulgari, Mulberry, Accessorize, Dior, JD and Tie Rack.
Airport operator BAA was unavailable for comment.
