Five new services to China helped London Heathrow Airport achieve a record high of 1.3m tonnes, up 1.5%, in the nine months to September 30.

Overall, revenues climbed 2.3% to £2.2bn “on the back of higher demand to fly and strong retail spend”, according to the airport.

It says progress continues on delivering expansion and the initial ground surveys of surrounding land began in September. “With two further public consultations set for January and June 2019, Heathrow remains on-track to submit a planning application in 2020 and for the first flights to use the new runway in 2026.”

Chief executive John Holland-Kaye said: “With the outcome of Brexit negotiations unknown, strong businesses like Heathrow must stand up to support Britain’s economy. We will expand Heathrow to boost Britain’s global trade for decades to come, and we are proud to protect Britain’s SMEs by maintaining our 30-day payment terms for all of our suppliers.
