British Airways will fly about 60% of its customers, even if cabin crew go ahead with their planned strike this weekend.

All flights to and from London City airport and all long haul services to and from Gatwick will continue to operate normally throughout any strike.

BA said that it has also rescheduled some services for strikes being arranged for beyond the weekend.

Earlier, Prime Minister Gordon Brown condemned the planned strike.

Mr Brown told BBC Radio 4′s Woman’s Hour that a strike would be “unjustified and deplorable”, and coming at “the wrong time”.

With a general election looming, Mr Brown’s comments are a rare direct intervention in an industrial dispute that involves one of the Party’s biggest donors.
