Emergency on BA825

A British Airways flight from Dublin to London Heathrow declared a mid-air emergency on Tuesday morning, prompting ground crews at the London airport to be placed on standby. The Airbus A321neo, operating as flight BA825, transmitted a squawk 7700 code – the international signal for a general emergency – while flying over north-west England, according to flight tracking data.

The aircraft, which departed Dublin Airport at around 8:45am, made a controlled descent to 8,000 feet before entering a holding pattern as the crew assessed the situation with air traffic control, as reported by Air Live and cited in multiple outlets. The flight landed safely at Heathrow shortly before 10am.

British Airways described the incident as a "minor technical issue" but did not provide further details, according to a spokesperson quoted in several reports. The airline declined to comment further.

One detailed account reported that the plane touched down at 09:40 BST and taxied to a remote stand of terminal 5 by 09:48 BST. The identity of the operational anomaly – whether related to cabin pressurization, engine performance, or an onboard medical situation – has not yet been officially confirmed by the airline, according to one report.

Standby at Heathrow

Emergency ground services at London Heathrow were alerted and placed on standby for the aircraft’s arrival as per standard protocol for 7700 declarations. The crew stabilised the aircraft at the lower altitude and entered a holding pattern while liaising with air traffic controllers.

Context of recent incidents

The flight incident comes after a "cyber security incident" affecting three major UK airports. Manchester Airport Group (MAG), which operates Manchester Airport, London Stansted, and East Midlands Airport, said criminal hackers accessed the data of almost nine million people. MAG reported that neither passenger safety nor aviation security was compromised during the incident.

MAG stated that neither the company nor the accessed system held customers' bank or payment details. The data accessed was mostly limited to customer email addresses and information related to wifi sign-ups within the airports' terminals. Phone numbers, vehicle registration numbers, and postcodes were also accessed, the company said.

Operations at all three airports remained "unaffected."

MAG's response

MAG stated that those responsible for the hack demanded a ransom fee, which was not paid. The company did not disclose the amount requested. MAG said it became aware of the attack last Tuesday.

A MAG spokesperson said last Thursday: "Manchester Airports group has been subject to a cyber security incident by an unauthorised third party." The company added that a quantity of customer data had been obtained relating to car park, lounge, and fast track bookings and in-airport wifi sign-ups at the affected airports. MAG said it immediately contained the incident and has been working with specialist advisers and relevant authorities.

MAG reassured customers that it takes the security of customer information extremely seriously and apologised for any inconvenience or concern caused.
