A number of passengers on Thursday (12 September) received text messages and emails telling them that their flights on 27 September had been cancelled.
It comes after BA was forced to cancel the “vast majority” of its flights on Monday and Tuesday (9-10 September) owing to a 48-hour strike by members of the Balpa union.
BA said it was contacting passengers in advance to offer them a full refund, or the opportunity to rebook on an alternative date, with an alternative airline, or to an alternative destination.
The airline added it was working with “more than 50 airlines” to ensure customers have alternatives.
