British Airways has grounded a transatlantic Boeing 777-200 after flight BA295 from London Heathrow to Chicago O’Hare suffered a reported loss of cabin pressure over the Irish Sea on 5 October and descended rapidly to about 9,000 feet before returning safely to Heathrow. The aircraft, registered G-VIIA, deployed oxygen masks during the incident and was later removed from the schedule while the case is examined.
Flight-tracking and aviation reports place the event roughly 40 nautical miles south of Dublin, where the crew initiated an emergency descent from cruising altitude. The aircraft levelled off at low altitude within minutes, dumped fuel and then turned back towards London. It landed safely at Heathrow after the long-haul service was abandoned.
The disruption affected a scheduled transatlantic rotation between two major hubs and briefly removed one of British Airways’ widebody aircraft from service. The underlying technical cause has not yet been confirmed in the available reporting, leaving the event focused on the operational response rather than a final fault diagnosis. The incident is being investigated, with passengers and crew reported safe after the return to base.
