The second round of strikes by Spanish airline Iberia is due to start on Monday.
Iberia and its subsidiaries Vueling, Iberia Express and Air Nostrum are due to cancel a total of 1,281 flights between March 4 and 8 in the second of three five-day strikes.
The action is in protest against a restructuring plan by parent IAG, which will lead to the loss of nearly 4,000 jobs at Iberia and a 15% cut in capacity.
Iberia will cancel 431 flights, Vueling 316, Air Nostrum 433 and Iberia Express 101.
The Spanish Public Works Ministry has established minimum services, with full schedules guaranteed to the Balearic and Canary Islands.
At least half of the normal flights will operate on international flights and those connecting Spanish cities over 500 kilometers apart.
At least 25% of services will be operating on internal flights of less than 500 kilometers.
Iberia says it plans to run 85% of long haul flights, 62% of medium haul and 47% of internal flights.
The strike action will also impact other airlines, including Turkish Airlines and Lufthansa, who contract ground services from the Spanish airline.
