British Airways cabin crew have announced seven days of strike action in the long-running dispute over pay.
Union members of its mixed fleet crew will walk out on March 3 to March 9.
The latest strike announcement follows a four-day stoppage, which ended Saturday.
BA said once contingency plans had been finalised it would publish more details next week.
Unite said it was clear BA could "afford" to settle the dispute after its parent company, IAG, announced annual pre-tax profit of £2bn last week.
Unite national officer Oliver Richardson said: "Striking mixed fleet cabin crew continue to demonstrate their determination to achieve a fair deal on pay in the face of British Airways' bully boy tactics."
BA said: "Our pay offer for mixed fleet crew is consistent with the deal accepted by 92% of colleagues across the airline, most of whom are represented by Unite.
"It also reflects pay awards given by other companies in the UK and will ensure that rewards for mixed fleet remain in line with those for cabin crew at our airline competitors."
Workers are striking in a dispute over pay for members on those contracts. They said they are underpaid and dispute the airline’s claim that staff are paid a minimum of £21,000 a year through pay, bonuses and incentives.
Unite has called for talks and conciliation service Acas.
