British Airways passengers face significant delays after a crew member accidentally activates an emergency slide, according to reports. The incident occurs on a flight scheduled to depart Montreal for London Heathrow on Saturday.

Outlets say the airline incurs substantial costs—reported as about £100,000—linked to the emergency slide activation, which requires equipment checks and operational disruption. The reports describe the event as accidental rather than related to an emergency during flight. The accounts focus on the impact on departure timing and the need to recover the aircraft for continued service.

While details are limited across the available reports, they consistently point to the same flight route, the date, and the core outcomes: the slide is triggered unintentionally, passengers experience delays, and British Airways faces a significant financial hit tied to the incident response and aircraft turnaround.
