Heathrow Airport expected 85m passengers in 2026 which represented a 0.6pc increase over the previous year.
The airport received approval from Westminster finance minister Rachel Reeves to proceed with a third runway planning process with a vote due later in 2026.
Owners paid dividends totalling £550m during the financial year.
Revenues reached £3.6bn while adjusted core earnings remained flat at £2bn and pre-tax profits fell to £575m from £917m in 2024.
New runway flights targeted 2035 with planning consent required by 2029.
Thomas Woldbye shared “Last year everyone at Heathrow rallied behind our ambition to deliver exceptional operational performance for our customers. Not only did we meet that goal, we surpassed it and achieved record-breaking service levels. With strong foundations in place and with the airport now operating very close to capacity, the next chapter is crucial to our success. Expansion will unlock significant economic benefits and create an extraordinary airport, fit for the future.”
