The BBC reports BA is exploring the sale of its Waterside base at Heathrow airport, which accommodated around 2,000 of its staff prior to the pandemic.
In a message to staff, seen by the BBC, BA’s director of people Stuart Kennedy said it was unclear "if such a large office will play a part" in the airline’s future.
Kennedy praised BA’s staff for their resilience after a swift and substantial transition to homeworking and remote working last March owing to Covid-19.
"We’ll want to consider what the ideal office layout for the future will be," said Kennedy. "Perhaps it’s less fixed desks and more casual meeting areas, and we need to consider colleague wellbeing too."
He added plans to sell Waterside were at a very early stage.
Both BA and parent IAG have had to make wide-ranging cost cuts over the past 12 months in response to the Covid crisis, which has seen BA dramatically reduce its operations, reduce staffing levels and move staff onto new contracts and pay structures.
On Thursday (18 March), IAG confirmed it was seeking to raise a further €1 billion through bonds, which will be put towards "general corporate purposes". IAG added the cash would help the group "withstand a more prolonged downturn in air travel" and ensure its carriers are ready to capitalise on an uptick in demand.
In a statement provided to the BBC, BA said: "The global pandemic has shown us that many of our colleagues enjoy working remotely and want to continue, and this has accelerated our approach to offering more agile and flexible ways of working.
"Our aim is to find a hybrid working model that suits our business, blending the best of office and remote working for our people. We’ve also re-structured our business to emerge from the crisis and are considering whether we still have the need for such a large headquarters building."
