British Airways cancels flight BA254 from Bridgetown, Barbados, to London Heathrow after reports that crew members became too intoxicated to operate the service. Multiple outlets report the incident involves alcohol consumption in a hotel bar or during time at a hotel associated with the crew before the scheduled departure, with some accounts describing a mix of drinks. The cancellation affects passengers bound for Heathrow, with reporting indicating up to 336 travelers are disrupted. British Airways confirms it is investigating the matter and says some crew members connected to the flight have been stood down or suspended pending the outcome. The airlines’ response focuses on internal review and temporary removal of relevant staff from duties while checks are carried out. The reports do not provide further verified details on the specific circumstances beyond allegations of pre-flight drinking, and the matter remains under investigation as described in the sources.
