British Airways cabin crew represented by UK union Unite and employed under the airline's "mixed fleet" contract will conduct a 48h strike later this month in a dispute over pay and conditions.
Unite says the strike will begin on 10 January after its members rejected a revised pay offer proposed by the airline in late December.
A majority of Unite members had voted for strike action on 14 December, after rejecting a 2% pay rise offer from BA. That industrial action had been due to take place on 25 and 26 December but was postponed to give cabin crew the opportunity to be balloted on the revised offer.
Unite says renewal of its strike plans follows its failure to hold "meaningful talks" with BA in the dispute, which centres on what the union says are "poverty pay" conditions at the carrier and a lack of collective bargaining rights for onboard customer service managers.
The union says it was required to take industrial action within 28 days of voting for it, unless the airline had agreed to an extension.
Unite national officer Oliver Richardson states: "Unite remains hopeful that a negotiated settlement which meets our members' aspirations can be achieved and would urge British Airways to engage constructively in meaningful talks to address poverty pay."
BA describes the strike as "unnecessary and completely unjustified". It says workers employed under its mixed-fleet contract represent 15% of its cabin crew and that it plans to "ensure that all our customers travel to their destinations" during the action.
The IAG-owned airline plans to publish its contingency plan on 6 January.
