British Airways will operate all its long-haul services to and from Heathrow and cancel short-haul flights during a three-day cabin crew strike this week.
Members of the Unite union will take industrial action from Thursday in a long-running dispute over pay.
BA cancelled 44 flights last week because of a 48-hour stoppage by members of the mixed fleet, made up of workers who have joined the airline since 2010.
BA said: “We have further strengthened our schedule for January 19-21, the days for which mixed fleet Unite has called strike action, and will fly all customers to their destinations.
“We will operate all our long-haul services to and from Heathrow and all services to and from Gatwick, London City and Stansted.
