AIRLINE Air Nostrum has announced plans to cancel 148 flights following a decision by transport workers to walk out.
Strike action by airport ground workers, pilots and train drivers is set to affect hundreds of thousands of holidaymakers.
Pilot union Sepla called for strike action in protest at the rising number of flights being transferred between airlines within the Iberia group.
This move comes has millions of Spaniards look to travel for Semana Santa and work stoppages cause ‘chaos’ at Madrid-Barajas airport.
Air Nostrum has said passengers affected by the cancellations can ask for a refund, or opt to travel on a different day before May 10.
The Valencia-based Air Nostrum has released a list of all the cancelled flights for April 15 -17 with more dates expected to be released.
