“The leisure market has been buoyant thanks to the half-term getaway, with our busiest day since July, and we are also seeing the gradual return of business travellers too,” the airport said in a statement on Friday.The hub said it is aware of potential strike action at a number of organisations, including a national Border Force strike, and it will have contingency plans in place to minimise any impact.“Heathrow, our airline partners and their handlers are all working together to make sure everyone can be reunited with their loved ones this Christmas.”Heathrow announced last month that its losses had widened, despite an improvement in passenger numbers, as the London airport warned demand may not recover “for a number of years”.“Headwinds of a global economic crisis, war in Ukraine and the impact of Covid-19 mean we are unlikely to return to pre-pandemic demand for a number of years, except at peak times,” it said in a statement.And the airport's underlying losses increased to £442 million ($503m) in the year to date, “as regulated income fails to cover costs, adding to the £4 billion in the prior two years”, it said."
