A strong summer saw Heathrow passenger numbers rise by a third to 59 million in the first nine months of the year as losses were cut.
The overall loss narrowed to £19 million against £442 million in the same nine-month period last year.
The summer saw 29 million travellers use the London hub as it provided connections to more than 214 destinations.
The fall in losses came “as we continue to focus on our strategy to manage costs and drive growth within a tight regulatory framework,” the airport said. Revenue rose by 30% to £2.7 billion
“Gearing is at historically low levels and our balance sheet is strong, with £4.6 billion of liquidity sufficient to cover all obligations for at least 24 months. No dividends are forecast for 2023.”
Heathrow described the Civil Aviation Authority’s future charging settlement as “challenging”.
But the airport plans “to continue investing in key upgrades to the airport with our transformative security programme, which is underway, and the supplier for the new Terminal 2 baggage system, which will be announced by the end of the year”.
More than £200 million is to be invested over there next three years to reduce carbon emissions.
Heathrow called on the government in next month’s Autumn Statement to “press ahead with pace” with a domestic sustainable aviation fuels industry, re-instate tax-free shopping for UK retailers and commit support to southern and western rail links to increase connectivity to the airport.
New chief executive Thomas Woldbye said: “Heathrow is already a great national asset for Britain – and our best days still lie ahead.
“We’ve got a clear plan to connect all of Britain to global growth, a flight path to net zero by 2050, and while we have a tight settlement from the CAA, we will upgrade the airport for our customers.
“I’m excited to take on the challenge and looking forward to working with Team Heathrow to build an even stronger hub for Britain in the next decade.“
