British Airways cabin crew will stage a fresh seven-day strike from 3 March in their dispute over pay, the Unite union has said.
The announcement comes during a four-day stoppage by BA staff that is due to finish on Saturday.
The airline said it had flown all customers to their destinations during all the strikes and would do so again.
BA said once contingency plans had been finalised it would publish more details next week.
Unite said the next planned stoppage will start at 00:01 on Friday 3 March and end at 23:59 on Thursday 9 March.
